Potential and Kinetic Energy

Front

What is Potential Energy (PE)?

Back

Potential Energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is Kinetic Energy (KE)?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass and speed of the object.

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

At which point is Kinetic Energy greatest in a roller coaster?

Back

Kinetic Energy is greatest at the lowest point of the roller coaster.

Front

Give an example of Potential Energy.

Back

A book on a shelf has Potential Energy because of its height.

Front

Give an example of Kinetic Energy.

Back

A moving car has Kinetic Energy due to its motion.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and the square of its velocity (KE = 1/2 mv²).

Front

What is the relationship between Potential Energy and height?

Back

Potential Energy increases with height; the higher an object is, the more Potential Energy it has.

Front

What is the formula for Potential Energy?

Back

Potential Energy (PE) = mass (m) × gravity (g) × height (h).

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases.
