Complicated dynamics problem using energy methods
Here we solve for the velocity of a disk as it's rolling up a circular hill using energy methods 1) Find work done by external forces (it's 0). 2) Notice there is rotation so the kinetic energy is 0.5 m (v2^2 - v1^2) + 0.5 I (w2^2 -...

An incline, 2 masses, and a pulley. What could be more fun?
A 55 g mass is attached to a light string, which is placed over a frictionless, massless pulley, and attached to a 199 g block which is on a board inclined at 39.3° as shown. Assuming the block starts at rest and the μk between the...

Practice Problem: Box Sliding Down a Ramp
Lisa, are you serious? Alright, just one more favor. This one is a little trickier than the previous, because there is some trigonometry involved, beyond the kinematics and friction from the previous problems. What will become of your...

Practice Problem: One-Dimensional Two-Body Problem
Lisa is moving again already! I dunno, I think there were bedbugs. This time you have a different plan, but you will still need kinematics and Newton's laws to find out how much time and effort stand between you and more snacks. Give it...

Mass vs. Weight and the Normal Force
Mass is just a fancy sciency word for weight, right? Wrong! Although related, they aren't the same thing. You'd better find out exactly what the difference is so that you don't look foolish around the water cooler!
