Kinetic & Potential Energy Flashcardizz Review

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

Which has more potential energy: a book on a shelf or a book on the floor?

Back

A book on a shelf has more potential energy because it is higher off the ground.

Front

What happens to potential energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy due to its position and tension.

Front

What type of energy does a moving skateboard have?

Back

A moving skateboard has kinetic energy.

Front

If two objects are at the same height, which one has more potential energy: a heavier object or a lighter object?

Back

The heavier object has more potential energy because potential energy depends on mass.

Front

What is the formula for kinetic energy?

Back

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

Front

What type of energy is present in a hammer held above a nail?

Back

The energy present is potential energy.
