Energy is the ability to do work. Energy can be thought of as a currency which is universally accepted as the way to make things happen. All moving objects have energy. The amount of energy depends on their speed and mass. The faster an object moves, the more energy it has, and the more work it can do on other objects with which it interacts.
Use evidence to construct an explanation relating the speed of an object to the energy of that object.
