Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object.

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.

How does mass affect Kinetic Energy?

Back

Increasing an object's mass increases its kinetic energy, as kinetic energy is directly proportional to mass.

Front

How does speed affect Kinetic Energy?

Back

Increasing an object's speed increases its kinetic energy, as kinetic energy is proportional to the square of the speed.

At which point on a roller coaster is Potential Energy the greatest?

Back

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

Front

Where is Kinetic Energy the greatest on a roller coaster?

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.
