Kinetic vs Potential Energy

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work. It is energy based on an object's position or condition.

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 its velocity.

Front

At which point is potential energy greatest in a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster.

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 formula for calculating 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 calculating 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

Give an example of potential energy.

Back

A rock at the edge of a cliff has potential energy due to its height above the ground.

Front

Give an example of kinetic energy.

Back

A moving car has kinetic energy due to its motion.

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 rolling ball have?

Back

A rolling ball has kinetic energy because it is in motion.
