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.

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

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

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass. The formula is KE = 1/2 mv², where m is mass and v is velocity.

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed. Doubling the speed quadruples the kinetic energy.

Front

What type of energy does food contain?

Back

Food contains potential energy, which is released when consumed.

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 relationship between Kinetic and Potential Energy in a pendulum?

Back

In a pendulum, potential energy is highest at the highest point, and kinetic energy is highest at the lowest point.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the potential energy held by an object because of its height above the ground, calculated as PE = mgh.

Front

What is the formula for Kinetic Energy?

Back

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