The four Kinematics Equations are useful for solving many different physics problems. Here I show you how to decide which equation to use when.

Elastic Collisions in One Dimension
In an elastic collision, momentum is conserved (as it is in most other collisions). However, an elastic collision also conserves kinetic energy, whereas an inelastic collision does not.
Periodic Motion: Period, Frequency Angular Frequency
Any kind of motion where the same action is repeated over and over again counts as periodic motion. This includes circular motion, the swinging of a pendulum, Hooke’s Law motion (bouncing spring) and wave motion.
Work & Energy – The Big Picture
(video) Here are three different ways to use work and energy to solve physics problems. If you’ve been studying this stuff for a while, you may find that this is what you need to put all the pieces together. Continue reading
