Potential and Kinetic Energy

Front

What is Kinetic Energy (KE)?

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.

What is the relationship between Kinetic Energy and mass?

Back

Kinetic Energy is directly proportional to the mass of the object; as mass increases, Kinetic Energy increases if velocity remains constant.

What is the relationship between Kinetic Energy and velocity?

Back

Kinetic Energy is proportional to the square of the velocity; if velocity doubles, Kinetic Energy increases by a factor of four.
