Why would it be hard to pedal a 10,000 pound bicycle? This simple explanation shows how Newton's 3 laws of motion might help you ride your bike.
A student in bed will remain in bed until acted upon by a large enough panic: The lesser-known Newton's 4th Law.
a student in motion will stay in motion until acted upon by a large enough sleepiness
completely true
Lmao so true, especially with COVID-19
lol
😭😭
Thank you for teaching in 3 minutes what my teacher couldn’t teach me in a week.
Lol
bruh
Lol 😂
when your teacher was the one who sent it to you :D
You probably didn't focus on the class. Don't always blame your teachers.
By far this is the perfect and easy explanation of Law of motion

You haven't played Artemis in Minecraft then...
3 hours worth of class compressed into 3 minutes worth of video
amazing...👏🏻👏🏻👏🏻
3 hours worth of useless class compressed into 3 minutes worth of video
I agree. 1 month of 1 hour 30 minute classes only to be explained easily in 3 minutes
I did my own experiment by hitting my dad, and he reacted.
if this only has 1 like it was me.
Lol
LOL
Lolll
I also liked my comment
These videos are gold
Cylde Dellafish they are not gold,but diamonds....
True
4 years later and without this i wouldnt be passing
A student will remain at rest, or will constantly binge watch, unless the force of realization of due work kicks in
Simple, Short but VERY useful. Thank you 🙃
they straight up made this man dummy thicc just to slow him down
yeah
Me after watching 2 videos about maths and science.
*Now i know everything in the universe, im even smarter than einstein*
Same
then go watch a VSauce video
11 years ago huh ty for that great video
Newton was really the true scientist who had changed the thinking habits of the people. Before him, people were facing the same kinds of problems but no one tried to find the reasons behind these happenings. I salute Newton for giving us a sense of thinking and imagining.
Sometimes, I feel Newton's third law of motion is forced to suite a narrattive, even when it doesn't necessarily explain a phenomena. It is hard to explain the applicability of the law in relations to the motion a bicycle. I think it is because the bicycle moves vertically, meanwhile the law suites horizontal motion. It better fits the working for a rocket going to space. But for a bicycle I find I awkward. Great video by the way
yes! it gets confusing when the directions change
ENGLISH!!!!
I was forced to watch this.
Zerospacedude dis my homework
same dude. for a test...
wiki page
I'm doing this for miss wasco XD

Newton's 4th law of motion -😃A book remains at rest and covered with dust until and unless some internal or external exam appears.😆 The speed of turning page is directly proportional to the syllabus to be covered and the tension remains constant. 😅🤣
🤣🤣
I have no words to and appreciate this explanation
This was very useful for doing my school work.
That's so cool bruh sub to my chaneeell
TEEJ no one cares
Thanks a lot! You helped me understand the lecture
thank you so much for this video! Simple and quick explanation! Keep up the good work!
could you please explain the 2nd one in a more specific way.i didn't get it so good
but it was awesome explanation.thank you
These videos are such a great way to refresh on things !
Thanks Bro, This video helped me a lot in Newton's law of motion.
Excellently Explained!!
perfect! this explains it quite well. Nice demonstrations and real world examples that are easy to "rap my head around", however I would have added a bit more arrows to illustrate more forces which were applied / left out.
I love this. It is so fun to learn about things. especially, science of all kinds, mathematics, computer programming, engineering, Etc.
Are you stalking me?
Todd Gobbett no!
I really like when topics are used to relate a scientific concept. Here is a series about Psychology within the context of bicycle prejudice: ua-cam.com/play/PLFOOfdNQa2zteDZZED-loSpz6SSxLtCDE.html
Wow, I understood it very clearly.
Thanks, mate! Really appreciate it!
Thank you for such an amazing explanation!
👇99% percentage of the people watching dis is from teachers or parents 👌
Nope not me
Yes😂
These videos are so valuable.
fr
Excellent video
please explain static friction and its relationship to the backward force of the tires to the ground
thank u so much, this totally helped
this really helped me understand better of newtons laws
Amazing Video!!
THIS VIDEO IS 11 YEARS OLD
loving this videos! thumbs up
thanks this really helped
Perfect explanation
Now I am too scared to ride my bicycle
Thank you so much
thx this really helped
thanks joshua, that was mildly interesting.
Ted is forever Ted. I love these lessons! @TED-Ed
Doesn't everyone?
This is super good!
Physics is really awesome! and thank you for this simple and understandable demonstration.
A fantastic and concise explanation for those looking to re-educate themselves after being out of school for some time.
This was an amazing video keep it up!
So if we all cycled East, we would make the world spin faster?
+Matthew Smith No lol. The Earth is so massive (literally "mass"ive"), and many people will end up on the sea floor within 1 sec
+Matthew Smith This actually happens every morning in major cities world-wide in the morning commute. It's just that with their commute home at night, the world is set right again.
+Matthew Smith yes it would, but by an amount so tiny it would be unmeasureable
Echelon Arts Photography Well not everyone go to work by travelling east, therefore if the people going east should balance people going west
Actually slower.. no?
How many cyclists does it take to let the earth spin at the speed of an average cyclist?
The earth already spins faster. It spins at about 1000 mph
The earth already spins faster. It spins at about 1000 mph
Divide mass of world by mass of cyclist. A person ways 70 kg whereas the earth ways something like 6,000,000,000,000,000,000,000,000 kg so we're talking something like more than 10,000,000,000,000 times more people than live on the planet atm.
1 thousand moles
way more than the population right now
thanks for teaching me in 3mins which 2 teachers couldnt teach me in a week.
I love videos like these.
Thank you
I love riding my bicycle!!
Excellent examples. Thanks!
awesome 1!
One question: How does the bike stay upright? When a person mounts a bike and stays still (no kickstand or legs, just the two bike tires) they fall over. But, we said person is moving it is really easy to stay up. However, no new force is applied in the left/right direction to help keep the bike up? So how does the bike stay up while it is in motion?
momentum... it is too "focused" on moving in one direction, that is to say it alleviates the potential of falling left or right like a domino. Remember that there is also air resistance... aerodynamics keep it aliened as well, much like an arrow flies straight and only straight, until an external force (such as wind or gravity) interferes. I hope this helped in answering your question.
Todd Gobbett But why do three wheelers stand upright even if they are not moving? why only vehicles having below 2 wheels fall down when not in motion? I mean my bicycle falls down but my car or tricycle doesn't when in rest.
blasttrash Because then the weight is more evenly distributed throughout the 3 given points. The tricycle has more surface area to support its centre of gravity. A bicycle or unicycle does not.
I believe the speed of the bicycle does not allow it enough time to be pushed over by air on either side. Or in other words, the force applied in propelling the bicycle forward is more than the force applied by the air on either side. Then there's also the fact that the centre of masses of you and the bicycle are properly aligned I guess. Todd Gobbett gave a pretty good explanation as well.
gilgamesh2399 actually these are all bad explanations
an arrow flies straight for a complitely different reason, air drag and gravity always work on it in flight
bicycle is not "too focused" on forward movement, there is no such quantity in physics
this is explained via precession, which is a very comlex mechanical concept that relies on the conservation of angular momentum
a frisbee flies, a spinning ball changes direction, a spinning top stays stable - all due to precession
thank you for asking questions
btw to anyone who got it wrong: props for trying, it is better than not analysing at all. :)
Nice video, but something missing or not directly stated, for Newton's 1st Law:
Objects at rest tend to stay at rest *unless acted upon by an outside force.*
Objects in motion tend to stay in motion with the same velocity (velocity is speed with direction, and depending on your frame of reference, it can be negative) *unless acted upon by an outside force.*
bruh he stated that, you need to apply force for your bicycle to start moving from rest but one it starts moving it becomes way esier to pedal.........
This is fantastic
Awesome explanation btw what application have ya used for the animation of this video pls do tell!
Can't believe Redbull ad saved my physics exam
Cảm ơn admin!
O ato de iniciar a pedalada em uma bicicleta demonstra-se potencialmente mais desafiador do que manter uma velocidade constante, em virtude de fatores que incluem a necessidade de superar a inércia inicial, equilibrar-se adequadamente, ajustar as marchas de maneira pertinente, lidar com resistências iniciais e coordenar meticulosamente os movimentos. Tais desafios, entretanto, tendem a ser progressivamente superados por meio da prática sistemática e da aquisição de habilidades específicas associadas ao processo inicial de movimentação.
Excellent...!!!
Thanks
Great study video.
Great study comment.
lol
Nice animations
Does a rubber pulled with equal force from both side an action reaction pair?
K WOW I LOVE TED TALK YOU LEGIT HAVE BEEN HELPING ME SO MUCH IN MY FINALS AH
....Thank you! A lot of people tried to explain it to me
So good help ful
This was actually a really nice animation
well done
Love this
Ted ed has become my favorite channel after i got my first A in maths and now they both are straight A's
i was forced to watch this
Good but why?
Only on the rear wheel with power does the ground's reaction force push forward, on the front it has an opposite effect, to counter the friction of ye olde wheel bearing and such. The reaction force arrow shall point towards the rear on the front tire I declare!!
How am I propelled to move in the forward direction due to the reaction force(Since the action force is balanced by the reaction force)
A Pharaoh in a tomb will keep sleep in a tomb, and a student on a bed will keep in his bed.🎉
What is the name of this music? It is simply great!
My teacher in middle school explained the 3rd law like punching a wall. The softer you hit the wall the softer the molecules in the wall hit back, the harder you hit it the harder they hit back at you and that's why it hurts
was. very good ❤
Thank so muc
A bicicleta move-se quando o ciclista pedala, transferindo a energia para as rodas através da corrente. A força nos pedais faz as rodas girarem, impulsionando a bicicleta para a frente.
Needed for Performa Task, we need 3 laws in one action IT REALLY HELPS CAUSE I ALSO NEED EXPLANATION❤
really affective
Newton and Bicycles??? My two favorite & most interesting things??? Awesome!!!!!
Wow it is amazing...
POV: your here from your science teacher telling you to watch this...
Yea- and we’re here close to the same time
That video gave the impression that the energy from the bouncing ball is all delivered to the floor that in return sends it back to the ball, is this accurate? I don't really have knowledge about physics but I have always thought that the bouncing ball bounces because it has less resistance to keep the energy in itself by contracting and releasing it by expanding. This also explains why the doesn't bounce off a surface that is softer than the ball itself. Please correct me if I'm wrong.
I believe it is a combination of both. Granted, you've probably learned this by now, since this comment was ten years ago, but for anyone else with the same question:
There are two parts to this. First, the ball delivers its energy to the ground, and the ground pushes it back. However, how much the ball actually bounces does depend on factors such as softness of the ground (softer absorbs more energy) and resistance of the ball, e.g., material and density. The second part is why rubber bouncing balls bounce better than hard, dense baseballs or soft, barely dense cotton balls.
Em resumo, a inércia é a resistência de um objeto à mudança em seu estado de movimento ou repouso devido à sua massa.
I was looking at an 11 minutes long video, and by minute 7, I still haven't understood a thing. I came here and this guy just explained it to me in three minutes... what a goat.
The crash course innit
Make a video about mendel laws.
omgg this is so helpful
magnificence!
2:20 well what if ball breaks the ground? Why does that happen and how will you explain that?
Same
How is it that TED education has so much better volume control than their regular videos on their director channel? The intro on that one is so much louder than the video itself.
Thank you! This will teach me a lot of things.
in the 3rd law ,is it an equal and an opposite reaction, or a reaction thats equal?they spoke differently in the 17th century than we do now.so did Newton word the 3rd law badly, or since we percieve/live in a 3 dimensional world are there two reactions to the original action?i.e. an equal reaction and an opposite reaction.
i always thought the 3rd law was worded badly. it should be "an equal opposite reaction",not "an equal and opposite reaction".
It's just one reaction. And yes it it worded somewhat unclearly.
this is a masterpiece
