Bowling Ball Pendulum
Bowling Ball Pendulum: Key Concept: Conservation of Energy Energy cannot be created or destroyed. It can only change form. There are two observable forms of energy, kinetic energy (or “energy in motion”) and potential energy (or “stored energy”). The total energy of a system is equal to the sum of its potential energy and its […]
Angular Momentum
Angular Momentum: What Is It? Let’s start with the basics. First of all, What is momentum? In order to understand momentum, we must first look at Newton’s Three Laws of Motion. 1st: A body in motion or at rest, will remain that way unless acted upon by some external force. EX.
