What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion. The more an object moves, the more kinetic energy it has.

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a ball held at a height has potential energy.

What happens to kinetic energy as an object moves from point C to D?

Back

Maximum kinetic energy starts to convert to potential energy as the object moves from point C to D.

What happens to potential energy as an object moves from point A to B?

Back

Maximum potential energy starts to convert to kinetic energy as the object moves from point A to B.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed; it can only be transferred or transformed from one form to another.

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on an object's position.

What does it mean for energy to be transferred?

Back

Energy transfer occurs when energy moves from one object or system to another, such as when a ball is thrown.
