AP® Physics 1: Forces and Newton's Laws (Unit 2)

In this video, I review Unit 2 of AP Physics 1: Dynamics (Forces and Newton's Laws)

Topics Covered: Forces, newton's first law, newton's second law, newton's third law, free body diagrams, gravitational force, normal force, applied force, forces at angles, force of friction, net force, coefficient of static friction, coefficient of dynamic friction, problems on inclined planes, systems of forces and weights, force of tension, kinematics

AP Physics 1 Learning Objectives 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, and 2.7

Stay tuned for the rest of the units! I plan to release them weekly.

Are you a high school student? I'm super impressed with your grasp of the subject matter, the learning/teaching process, animation/video production, comedy, time management, not to mention your work ethic. You're gonna do great things when they finally let you loose in the big world. It's kids like you that renew my faith in the American educational system and my faith in humanity, which has been shaken to the core in recent years. I hope your parents read this and give themselves a giant pat on the back.

OMG YOUR VIDEO TAUGHT ME MORE IN 7 MINUTES THAN MY PROFESSOR IN 10 YEARS THANKS OMG!

[andreazgarcia]

No other physics ap videos have this production quality. Keep it up

[siel.castillo]

Will you be continuing this series? Your style of teaching this is excellent and I(as well as the other students) would appreciate more content.

[navybee]

Just got a 100 on my unit 2 test thanks to this!

[Ali-F]

Absolutely amazing, helping me slide through my AP Physics course.

[rinstorm]

Your channels helping so much!! Thank you!! I hope you make more of these

1 small problem is that Normal Force and Force of Gravity are not "Equal and opposite" (all of the time). Newtons third law doesn't apply like this. Although frequently you can treat them as opposites if they are on a flat surface, the opposite force has to be directly related. For instance, the opposite of the normal force of the block on the table is the force of the table on the block, and the opposite of the force of gravity of the earth on the person is the force of gravity of the person on the earth.

Please keep on doing AP Physics videos

[ladindustries]

can't believe these don't have more views. The videos are of high quality and concise. Great work mate!

[jamesv]

Bro this is so good u should have more views

[corbsofthewest]

The only issue I have is that you used normal force as an example of Newton’s third law and treated gravity and normal force as a force pair when they aren’t, they can’t be bc Newton’s third law requires two object to interact. The normal force and gravity is acting on one object. However there is a gravity field of the object that is exerting the same gravitational force as earth does onto it due to Newton’s third law

[harrisonlee]

btw for anyone who's watching F perp is usually denoted as the force parallel to the surface not the normal force. very good video other than that.

[sacsarinai]

At 3:40 you make a common mistake: Normal force and Gravity are NOT Newtonʻs third law forces. The 3rd law force that counteracts gravity on the book (by the earth) is the force of gravity pulling up on the earth (by the book)!

[mxologies]

i think you forgot about elevators in this unit

[bluez]

can you plaese do unti 3 which is work and energy pls

[annabellipkie]

helped me review 10 mintues before my test 😟

[lunacatt]

3:30 This is just incorrect, FN and Fg are not N3L force pairs. I am surprise at how you managed to make such a simple mistake

[ilikeapples]

Man come back to physics bro this yo calling u a genius
