Potential & Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. For example, an apple sitting on the edge of a table has potential energy because of its height.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has.

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 Speed?

Back

Speed is the measure of how fast an object is moving. It can increase, decrease, or stay the same.

Front

When do you have maximum kinetic energy on a roller coaster?

Back

You have maximum kinetic energy at the bottom of each hill on a roller coaster.

Front

What is an example of potential energy?

Back

An example of potential energy is a rock held at the top of a cliff.

Front

What is an example of kinetic energy?

Back

An example of kinetic energy is a ball rolling down a hill.

Front

How does gravity affect potential energy?

Back

Gravity affects potential energy by pulling objects down, which decreases their potential energy as they fall.

Front

What is the relationship between potential and kinetic energy?

Back

The relationship is that as potential energy decreases, kinetic energy increases, and vice versa.

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.
