Newton's 1st Law of Motion | Physics - Forces & Newton's Laws
In this video we'll learn about net force, balanced and unbalanced forces, Newton's 1st Law of Motion and how to explain different examples of motion using Newton's first law.
Newton's 1st law: An object at rest will remain at rest and an object in motion will continue moving in a straight line at a constant speed unless acted on by a net force.

TYSM THIS HELPED A LOT KEEP IT UP 🙏👍🏾
What a logical and efficient system, I hope that a country that loves to feel especial does not use objects that vary in size or body parts to define distances or mass.
Thank you so much! this helped me a lot💗
by far best one ive watched
Thanks!

I still don't understand why we always use (-g) whether the object is going up or down
Yeah that's a common point of confusion. The acceleration of g (9.8 m/s²) is caused by gravity, which always acts downwards no matter what's happening, gravity and the acceleration never act upwards. So even if an object is moving up (it's velocity is up) the acceleration is still down. That has the effect of slowing down the speed of an object moving up, and speeding up an object if it's moving down. Does that help or still confused?
Thank u I'm a senior this my last year and u helped me understand a lot 💕💕💕💕💕
Best Physics Teacher!!

we have make all the number to have only one number in the left?
Yup if you are writing a number in scientific notation you would move the decimal until there is one digit to the left of it. The number of places you moved the decimal is the exponent above the 10 (the exponent is positive if you moved the decimal left and negative if you moved it right).
you r amazing nd i lke you thanks a apreciate that
i love you thanks for these videos. you're awesome, i get it better than anything else
Awesome I’m glad they’re helping!
Greatly appreciated .. 👏
This formal is so good Im gonna tell my teacher to recommend your videos for her future classes

My professor didn't explain none of this. He just barely read from some slides. You're a lifesaver man.
They all do dont they!
MY GOAT. THANK YOU
🎉🎉 bro thank you, i really understood the basics wih this video and well! I was not doing well in my calc or static dynamics class because my foundations in trig were terrible! I really feel like i have a great understanding now! Thank you so much and keep uploading please!
Awesome, I’m glad it was helpful!
brUHHH THANK TOU❤
Thank you so much , it's been two months since i've been studying physics but it's now that i understood prefixes and scientific notaions !!! Thanks alot❤
I’m glad it helped!
i understand why we use a tangential line to describe the linear velocity's direction but why cant we use the same for displacement?? why is linear displacement's direction described as the arc of the circular track and not the tangent because the direction of velocity vector should be same as displacement right?
That's a great question! I'm not sure if I have a good answer for you, some of it just comes down to the words we use to describe different things. The word "displacement" by itself already has a definition, which is the straight line distance between a start and end point. For example if a car drove 1/4 of the way around a circle, it's "displacement" is the straight line distance between the two points and I use the words "tangential displacement" to describe the arc length of the car's path. I could have just used "arc length" or "distance" instead, but I used "tangential displacement" because displacement is a vector which can be positive or negative, and we need to include whether that arc length is positive or negative based on the axis we set up. For an object in circular motion the "tangential displacement" will always be an arc length that curves around a circle, so it can't be along a straight line tangent to the circle. If an object was moving in a straight line then the displacement would be in the same direction as the velocity. But for an object in circular motion the direction of the tangential velocity is constantly changing, so the displacement is not in the same straight line direction as the velocity (there is no single direction of the velocity). I can see how this stuff can be confusing, hopefully that helps a little bit!
@@physicslab42 thanks a lot very helpful dude
your explanation talent is out of this world. I kind of wish I had at least a quarter of it.
easy to understand thank you
well explained sir/A projectile is a name given to a body which is given an initial velocity at an angle OTHER THAN 90 degrees and then allowed to fall under the influence of gravity. ua-cam.com/video/0tq4fO16NLE/v-deo.html
I really appreciate this guy doing this major favour for us 💕
When are you gonna upload new video
Keep going🔥
I hope you upload video lectures about other concepts in classical physics like Newton's Laws of Motion, Momentum, Forces, etc... I'm looking forward to it.
Thanks, I plan to!
This is a great video, from the graphics to the pace of instruction. I was really engaged. I also appreciate the practice problems. Keep up the good work.
Thanks! I’m glad you enjoyed it!
Where would I be without you? I will tell you taking college physics for once again. Thank you for helping me to understand what my professors could not.
Thx

I swear you are literally saving my educational life, mad love for you and what you do
