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. It is energy at rest.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

Give an example of potential energy.

Back

A hammer held above a nail has potential energy because it is positioned to fall.

Front

Give an example of kinetic energy.

Back

A sled sliding down a snowy hill has kinetic energy because it is in motion.

Front

What happens to potential energy when an object moves?

Back

As an object moves and falls, its potential energy is converted into kinetic energy.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, depending on the object's position and motion.

Front

What type of energy does a pile of coal represent?

Back

A pile of coal represents potential energy because it can be used as fuel.

Front

What type of energy does a flag blowing in the wind represent?

Back

A flag blowing in the wind represents kinetic energy because it is moving.

Front

How can you increase the potential energy of an object?

Back

You can increase the potential energy of an object by raising it to a higher position.

Front

How can you decrease the kinetic energy of an object?

Back

You can decrease the kinetic energy of an object by slowing it down or stopping it.
