Calculating Potential & Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is 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 Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object as a result of its height above the ground. It is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more kinetic energy it has. Kinetic energy increases with the square of the velocity.

Front

What is the formula for calculating Potential Energy?

Back

The formula for calculating Potential Energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What type of energy does a battery store?

Back

A battery stores Potential Energy.

Front

If an object is at rest, what type of energy does it have?

Back

An object at rest has Potential Energy, but no Kinetic Energy.

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 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 unit of energy in the International System of Units (SI)?

Back

The unit of energy in the SI system is the Joule (J).
