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. For example, a book on a shelf 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 moving car or a rolling ball has kinetic energy.

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 the relationship between potential and kinetic energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest points of the swing, while kinetic energy is highest at the lowest point.

Front

Can an object have both potential and kinetic energy at the same time?

Back

Yes, an object can have both types of energy. For example, a person climbing a ladder has potential energy due to height and kinetic energy due to movement.

Front

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

Back

A rock at the top of a hill has only potential energy until it starts to roll down.

Front

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

Back

A car driving down the road has only kinetic energy as it is in motion.

Front

At which point in a swing is kinetic energy the highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

At which point in a swing is potential energy the highest?

Back

Potential energy is highest at the highest points of the swing.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.
