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 has the potential to do work when released.

Front

What is kinetic energy?

Back

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

Front

How does potential energy change as an object falls?

Back

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

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy.

Front

At which point in a pendulum's swing is potential energy the greatest?

Back

Potential energy is greatest at the highest point of the swing.

Front

What type of energy does a rock have at the edge of a cliff?

Back

A rock at the edge of a cliff has potential energy.

Front

Give an example of potential energy.

Back

An example of potential energy is a pulled back string on an archer's bow.

Front

What happens to kinetic energy when a roller coaster goes down a hill?

Back

The kinetic energy increases as the roller coaster descends.

Front

What is the relationship between potential and kinetic energy in a closed system?

Back

In a closed system, the total energy remains constant; as potential energy decreases, kinetic energy increases, and vice versa.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.
