Energy, Work, and Power

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy stored in an object due to its height above the ground. The higher the object, the more gravitational potential energy it has.

Front

What type of energy is stored when you stretch a rubber band?

Back

When you stretch a rubber band, you are storing potential energy.

Front

What is the formula to calculate work?

Back

Work is calculated using the formula: Work = Power × Time.

Front

What is kinetic energy?

Back

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

Front

How does speed affect kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is power in terms of energy?

Back

Power is the rate at which work is done or energy is transferred. It is measured in watts.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

Front

What is the relationship between work, power, and time?

Back

Power is the amount of work done per unit of time.

Front

What happens to potential energy when an object falls?

Back

When an object falls, its gravitational potential energy is converted into kinetic energy.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a rolling ball or a running person.
