The video explains a required physics practical activity that investigates the relationship between the acceleration of an object and its mass, keeping the force constant. The experiment uses a trolley being accelerated by the weight of...

Review of all of the Dynamics topics covered in the AP Physics 1 curriculum.

Review of the Simple Harmonic Motion topics covered in the AP Physics 1 curriculum.

Given certain parameters, how would you solve this problem in X direction?<br/>
Newton's Laws Of Motion With Friction, Part 3

By the time students learn about all the equations for mechanical energy, momentum, impulse and impact force, they often start to confuse the equations with one another. This is a straightforward, simple look at all of those equations...

Electricity makes our lives easier every day. We use electricity in our work and play. Because electricity is virtually unseen, it is often difficult to understand just where it comes from and how it works. By watching the video and...

This problem is from the Meriam and Kraige Statics textbook. I do not own this problem and I am not using it for commercial purposes.



In this problem you need to always start with a free body diagram. Notice that in order to...

In this video, we explore the under-appreciated 5th quadricep muscle, articularis genus, by examining its structure, origin, insertion, action, innervation, and overall function.

Calculus based review of Newton’s three laws, basic forces in dynamics such as the force of gravity, force normal, force of tension, force applied, force of friction, free body diagrams, translational equilibrium, the drag or resistive...

Unboxing an MIT Physics Exam from the 8.012 Classical Mechanics course, plus we go over my answers on the hardest exam I took at MIT in physics (argh!) and discuss exam tips and tricks from 6:51.

Static Friction Summary

Slope-style skiing is a gravity defying freestyle skiing event debuting in Sochi. Nick Goepper, a 2013 world champion, will need to follow the laws of physics and rotational motion in order to nail his tricks in his quest for Olympic...

In this video I cover some of the main formulas used for a standard dynamics course:

1) Plane m
otion
2) Project
ile motion
3)
Circular motion
4) Dry Friction
(static and dynamic)
5) Relative motion (for no

Billy helps you review Conservation of Mechanical Energy, springs, inclines, and uniformly accelerated motion all in one example problem.

The maximum friction force that can be a applied on a stationary object is F_max = u_s N

Here we solve for the velocity of a block as it's sliding up a circular hill using energy methods 1) Find work done by external forces (it's 0). 2) Notice there is negligible rotation so the kinetic energy is just 0.5 m (v2^2 - v1^2). 3)...

A wheel that spins forever; a bird that never quenches its thirst; a clock that never stops ticking, an endless source of free energy. These are but the dreams of inventors striving to make perpetual motion machines, machines that can...

Learn how to use Mechanical Energy when the Work done by Friction does not equal zero.

A book is resting on a board. One end of the board is slowly raised. The book starts to slide when the incline angle is 15°. What is the coefficient of static friction between the book and the incline?

When light passes through the universe and is redshifted by the expansion of space itself, how is energy conserved? The stretched light has a longer wavelength and therefore a lower energy. Is energy conserved? If so, where does it go?

You place a book on a 14° incline and then let go of the book. If the book takes 2.05 seconds to travel 0.78 meters, what is the coefficient of kinetic friction between the book and the incline?
