What is the Law of Conservation of Energy?
The law of conservation of energy tells us that energy is neither created or destroyed - just converted from one form to another. This means that we cannot make energy from nothing and energy does not just disappear. Energy, however, can...

Kinetic Energy and Potential Energy Explained - what's the difference??
Energy is all around us. There are two main types of energy - kinetic energy and potential energy. Kinetic energy is the energy of motion and potential energy is stored energy. In this video, we will cover both kinetic and potential...

How to Calculate Kinetic Energy (KE)
The kinetic energy of an object is based on the mass of the object and it's velocity. The more mass an object has, the more kinetic energy it has and the faster the object is moving, the more kinetic energy an object has. The formula...
