Kinetic and Potential 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 is often associated with gravitational potential energy, calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).

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.

Front

What is the difference between Kinetic and Potential Energy?

Back

Kinetic Energy is energy of motion, while Potential Energy is stored energy based on an object's position or state.

Front

How does height affect Potential Energy?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity, represented by the formula p = mv.

Front

What is the unit for momentum?

Back

The unit for momentum is kg m/sec.

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

What type of energy does a moving skateboard have?

Back

A moving skateboard has Kinetic Energy.
