IQWST PS2 Lessons 1-4

Front

What is Kinetic Energy?

Back

Energy due to motion. It is the energy an object possesses because of its movement.

Front

What is Potential Energy?

Back

Stored energy that depends on an object's position or state. It can be converted into kinetic energy.

Front

Give an example of kinetic energy.

Back

A car driving down the road.

Front

Give an example of potential energy.

Back

A book on a shelf.

Front

What happens to kinetic energy when an object slows down?

Back

The kinetic energy decreases.

Front

What happens to potential energy when an object falls?

Back

The potential energy decreases and is converted into kinetic energy.

Front

At which point in a pendulum's swing is kinetic energy highest?

Back

At the lowest point of the swing.

Front

What is the relationship between kinetic and potential energy in a roller coaster?

Back

As the coaster climbs, kinetic energy is converted to potential energy; as it descends, potential energy is converted back to kinetic energy.

Front

What is the formula for kinetic energy?

Back

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

Front

What is the formula for potential energy?

Back

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