What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a roller coaster at the top of a hill has high potential energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

Front

What is mechanical energy?

Back

Mechanical energy is the total energy of an object, which is the sum of its potential energy and kinetic energy.

Front

How does potential energy change as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, keeping the total mechanical energy constant.

Front

What happens to kinetic energy when an object speeds up?

Back

When an object speeds up, its kinetic energy increases.

Front

What is the relationship between potential energy and height?

Back

Potential energy increases with height. The higher an object is, the more potential energy it has.

Front

What is an example of potential energy in everyday life?

Back

A stretched rubber band has potential energy because it is stored energy that can do work when released.

Front

What is an example of kinetic energy in everyday life?

Back

A moving car has kinetic energy because it is in motion.

Front

What is the law of conservation of energy?

Back

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

Front

What happens to energy during a roller coaster ride?

Back

During a roller coaster ride, energy transforms between potential and kinetic energy as the coaster moves up and down.
