4.PS3.2 - 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 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. For example, a rolling ball has kinetic energy because it is moving.

Front

At which point does an object have the most potential energy?

Back

An object has the most potential energy at its highest point.

Front

At which point does an object have the most kinetic energy?

Back

An object has the most kinetic energy at its lowest point or when it is moving the fastest.

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 gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground. It is calculated using the formula: PE = mgh (mass x gravity x height).

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in objects that can be stretched or compressed, like springs or rubber bands.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like food or fuel.

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 increase the kinetic energy of an object?

Back

You can increase the kinetic energy of an object by increasing its speed.
