Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

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 gravitational potential energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

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 an example of Kinetic Energy?

Back

A moving car, a running dog, or a thrown ball are all examples of kinetic energy.

Front

What is an example of Potential Energy?

Back

A book on a shelf, a stretched rubber band, or water stored in a dam are examples of potential energy.

Front

Where is Potential Energy greatest in a roller coaster?

Back

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

Front

Where is Kinetic Energy greatest in a roller coaster?

Back

Kinetic energy is greatest at the lowest point of the roller coaster, where the speed is highest.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has potential energy due to its position.
