Potential and Kinetic Energy Review Bell Ringer

Front

What is Potential Energy (PE)?

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 (KE)?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass and speed of the object.

Front

Where is maximum potential energy found on a roller coaster?

Back

At the top of a big hill.

Front

What happens to potential energy as a rock falls off a cliff?

Back

The potential energy decreases as the kinetic energy increases.

Front

What type of energy is stored when you compress a spring?

Back

Elastic energy.

Front

What is the formula for calculating Kinetic Energy?

Back

KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for calculating Potential Energy?

Back

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

Front

Give an example of an object with high potential energy.

Back

A book placed on a high shelf.

Front

Give an example of an object with high kinetic energy.

Back

A moving car.

Front

What happens to energy during a roller coaster ride?

Back

Energy transforms between potential and kinetic energy as the coaster moves up and down.
