Mini-Quiz: Proof that Work Can be the Change in Kinetic Energy

by Ron Kurtus (29 November 2013)

Take this Mini-Quiz to check your understanding of the lesson material.



1. How is the change in kinetic energy designated?

KE − KE = 0

KE change

ΔKE

2. What is the standard work against inertia equation?

W = mad

W = mgd

W = mid

3. How do you prove the equation?

Break work against inertia equation into its components

You can't prove it with the information given

Substitute variables and solve for x

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.


It takes energy to do good work
