Identifying Kinetic and Potential Energy

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

What is Potential Energy?

Back

Potential energy is the stored energy of an object due to its position or state. It has the potential to do work in the future.

Front

Give an example of Kinetic Energy.

Back

A moving car, a running dog, or a spinning top are all examples of kinetic energy.

Front

Give an example of Potential Energy.

Back

A book on a shelf, a drawn bow, or water stored in a dam are examples of potential energy.

Front

What happens to Potential Energy when an object is in motion?

Back

When an object is in motion, its potential energy is converted into kinetic energy.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the more potential energy it has due to gravity.

Front

What is the formula for Kinetic Energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

The formula for potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

Can an object have both Kinetic and Potential Energy at the same time?

Back

Yes, an object can have both types of energy, such as a roller coaster at the top of a hill (potential) that is about to descend (kinetic).

Front

What is an example of an object with no energy in the system?

Back

A stationary object that is not capable of moving or changing, like a rock on the ground.
