Forms of Energy

Front

What is potential energy?

Back

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

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a moving car or a rolling ball has kinetic energy.

Front

Which has more potential energy: a ball on the ground or a ball on a table?

Back

A ball on a table has more potential energy because it is higher off the ground.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy when an object moves. For example, when a roller coaster descends, potential energy is converted to kinetic energy.

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting potential energy to kinetic energy.

Front

What is an example of energy in motion?

Back

A bicycle moving down a hill is an example of energy in motion, which is kinetic energy.

Front

What is the meaning of 'convert' in terms of energy?

Back

To convert means to change energy from one form to another.

Front

What type of energy does a stationary car have?

Back

A stationary car has potential energy because it is not moving but has the potential to move.

Front

What type of energy does a speeding car have?

Back

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