In this lesson, you will learn about Newton's second law of motion in physics. Newtons 2nd law describes how forces and motion are connected. Specifically, forces cause motion to change, that is, forces cause objects to accelerate. The famous equation F=ma mathematically shows how forces, mass, and acceleration are connected. Note that a force is not needed for motion occur once it has already begun. Rather, forces in newtonian mechanics cause the state of motion to change. That is, forces cause objects to speed up or slow down, or they cause objects to change direction, which is also an acceleration.

I love the way he explains everything he explains I'm able to understand very easily, I really appreciate his lectures ❤️
So nice of you!
@@MathAndScienceTHE UNDERSTANDING OF WHAT ARE GALACTIC JETS AND THE SOLUTION TO WHAT IS THE CORONAL HEATING “PROBLEM”:
Consider what is E=MC2. The stars AND PLANETS are POINTS in the night sky ON BALANCE. Two AND three dimensional SPACE are BALANCED. Great. (Indeed, consider TIME AND time dilation ON BALANCE.) This CLEARLY solves what is the coronal heating “problem”. REGARDING WHAT IS E=MC2, c squared CLEARLY AND NECESSARILY represents a dimension of SPACE (ON BALANCE). Great. I have CLEARLY proven what is the FOURTH DIMENSION. ELECTROMAGNETISM/energy is gravity.
What is E=MC2 is the reason why what are OBJECTS may fall at the SAME RATE. Great !!!!

Consider what is THE EYE ON BALANCE. Notice what is the BLUE sky. ELECTROMAGNETISM/energy is gravity.

I love how you actually explain the equations! It makes way more sense than plugging in numbers, it helps a lot with complex questions!
This was the video that made me understand physics after a year of taking the class
Marvellous. Genius, the best tutor I have ever seen... greating from Egypt
Jason is brilliant!!
Love this explanation!
You make everything easier to me sir!!
Hi sir, you helped me a lot a lot a lot !! you have skills in teaching !
Excellent explanation.
i don't have words.....its simply outstanding....
Thanks!
This video triggered (within me) a much more complete picture of understanding AND applying: Force = mass x acceleration. Which has already triggered a few tinkering scenarios of just reasoning with energy and forces. Sometimes you just struggle learning, because the teacher/book can't find the right key to unlock the potential of a mind.
What switched ON my light bulb here (along with video 1-5-1), was your hard reasoning - what's what.
Thank you for these lessons ❤
Welcome!
Thank you very much dear teacher
oh my gosh ! I so love this teacher! Thank you so much! God bless
I understod physics now! Thank you!
Life made easier, thanks for the clear and informative delivery
Glad it helped!
You are the best👌🏼🔥
THANK YOU... SIR...!!!
10x very much sir lcan't hesitate to watch your videos💕💕💕
Thankyou sir for your hardwork love from India 🇮🇳
You do awesome videos....I am able to answer very will in my school...
Awesome!
Thinking about this in terms of thrusters, though (like a deceleration maneuver), you have to realize that to get the force applied in the opposite direction, you'd have to swivel the thrusters so the burn would now face in the direction you're currently heading, in order to counteract the forward velocity. Those Force lines can seem backwards if you don't think about the mechanism behind it all (at least for me), because at first I got them confused with the direction the thrusters were firing. My brain is weird.
For real , let you glow to us understanding because whenever I feel like adding on knowledge believe I watch your sweet educative and "positively" impactial to whatever I do. I dought no for subscribing this channel.
Nice 👍
Love you sir from Pakistan. Because of you i scored a lot of marks in my Maths and Statistics final paper❤❤
Thanks for explaining that perfectly. Although English is not my first language but I comprehend it better than the explanation of my own teacher.
Thank you, your teaching is so clear and understandable
Love you sir, very nice, you are full of knowledge ❤
Best teacher..❤❤
Thank you!
Thank you sir you are more better than my professor from 🇳🇬
This guy is damn good. Keep up the good work, and thank you.
Part 2 sir !!!!
What is E=MC2 is taken directly from F=ma.
My main takeaway was the set of units [N, kg, m/s^2]. And a bit of OCD - in that the second ship at 28:45 never got its windshield :(
What Is relationship between mass and acceleration
Can I ask sir? What if the mass is not given in the question?
You will list five differences between mass and weight by litter
Doesn't the mass or weight of an object not count in space, except when under the influence of gravity from some world or other cosmic body?
How can we know how to use sin or cos
Sir I understood a lot from you.
But the problem was that when you said Force is in the same direction as acceleration, I wondered about the Centripetal Force towards the center of motion when an object moves in a circle. Isn’t the direction of force and acceleration different??
Great question! The force and acceleration are ALWAYS in the same direction, even for circular motion. Take the example of a planet orbiting the sun in a circular orbit. Where is the force on the planet? It is the force of gravity directed radially inward toward the sun. This force is pointed to the center of the circle. The centripetal acceleration is ALSO pointed to the center of the sun. Same direction.
@@MathAndScience great 👍
@@MathAndScience I was going to comment the same thing, But now I know
ask acceleration distance
When you dont understand everything its like your in this dark place,but then sometimes there is a thing that clicks inside you that takes you to a brighter place. For those of us who want to understand its like a sunny day
Awesome!
Sir the question is is . Force =14.0N why you add a etra 0

a=f/m
140.0 n force
a=4.31 m/s2
4.31 m/s2
4.31 n/kg
140/32.50=4
32.50x3=9750
140-128= 12
32.50/140.0=4
32.50x3= 97.50
140/32=4
1 meter
32.50/32.50=1
100/32.50=3
100-97.50= 2.50
back and fourth
140-130=10
12/2=6
32.50x4= 130.00
1000-9750= 250
10.00 s
32x4= 128
a=140.0 n/32.50 kg
32.50x4= 13000
10.00/1=1/1=101m
30+2.50=32.50
F=MA
10.00 s time
formula
32.50 kg mass
101 meters
10 s x2=20 s
Woot
Even a nine year old would understand this easily, and trust me I KNOW because I am 9
1m/60 seconds=m/10.00 s
This explanation of Force is right up there with good Vibrations, & I use to think it was just a cool song.I love apples & now I'm thinking about Newtons when I eat one. 🙂
hahahaha
Nice 👍
Thank you! Cheers!
👍❤🌷👍
100/32.50=3
