Potential and Kinetic Energy

Front

What is potential energy?

Back

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

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. For example, a rolling ball has kinetic energy.

Front

What happens to potential energy when an object falls?

Back

When an object falls, its potential energy decreases while its kinetic energy increases as it speeds up.

Front

Can you give an example of potential energy?

Back

An example of potential energy is a stretched rubber band. It has stored energy due to its position.

Front

Can you give an example of kinetic energy?

Back

An example of kinetic energy is a car driving down the road. It is in motion and has kinetic energy.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy. For example, when a roller coaster goes down a hill, its potential energy turns into kinetic energy.

Front

What is gravitational potential energy?

Back

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

Front

What factors affect kinetic energy?

Back

Kinetic energy depends on the mass of the object and its speed. The formula is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is an example of an object with high potential energy?

Back

A boulder sitting at the edge of a cliff has high potential energy due to its height.

Front

What is an example of an object with low kinetic energy?

Back

A slow-moving bicycle has low kinetic energy compared to a fast-moving car.
