Potential and Kinetic Energy

Front

What is potential energy?

Back

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

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 sum of potential energy and kinetic energy in an object that is used to do work.

How does energy transform when riding a bicycle?

Back

When riding a bicycle, chemical energy from the rider's muscles is transformed into mechanical energy to move the bike.

Front

What happens to potential energy as an object falls?

Back

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

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 type of energy is used to cook food in an oven?

Back

Heat energy is used to cook food in an oven.

Front

What is an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a moving car or a flowing river.

Front

What happens to a skier's energy as they go up a mountain?

Back

As a skier goes up a mountain, their potential energy increases due to the height gained.

Front

Which has more kinetic energy: a fast-moving car or a slow-moving bicycle?

Back

A fast-moving car has more kinetic energy than a slow-moving bicycle.
