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 be converted into kinetic 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 the speed at which it is moving.

What type of energy is stored in gasoline in a car tank when the car is not running?

Back

Potential Energy.

Front

As a pendulum swings from its highest to lowest position, what happens to its potential and kinetic energy?

Back

The potential energy decreases while the kinetic energy increases.

Front

In a swing, when is the potential energy the highest?

Back

The potential energy is highest at the highest points of the swing (points X and Z).

Front

In a swing, when is the kinetic energy the highest?

Back

The kinetic energy is highest at the lowest point of the swing (point Y).

Front

What happens to the energy of a rubber band when it is pulled back but not released?

Back

It has potential energy stored in it.

Front

Which of the following has kinetic energy? a. a car parked on a steep hill, b. a tennis ball rolling across the court, c. a picture hanging on the wall, d. a piece of coal before it's burned

Back

b. a tennis ball rolling across the court.

Front

What is the formula for calculating kinetic energy?

Back

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

Front

What is the formula for calculating potential energy?

Back

Potential Energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.
