Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object possesses due to its motion, which depends on its mass and speed.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as height above the ground.

Front

How is Kinetic Energy calculated?

Back

Kinetic energy (KE) is calculated using the formula KE = 1/2 mv², where m is mass and v is speed.

Front

How is Potential Energy calculated?

Back

Potential energy (PE) is calculated using the formula 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 has kinetic energy due to its motion.

Front

What is an example of Potential Energy?

Back

A book on a shelf has potential energy due to its height above the ground.

Front

At what point does a roller coaster have the greatest Kinetic Energy?

Back

A roller coaster has the greatest kinetic energy at the bottom of the tallest hill.

Front

What is the relationship between Potential and Kinetic 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 the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.
