What is Kinetic Energy?

Back

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

How does mass affect Kinetic Energy?

Back

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

What is the relationship between speed and Kinetic Energy?

Back

Kinetic Energy is proportional to the square of the speed; if the speed of an object doubles, its Kinetic Energy increases by a factor of four.

When is Kinetic Energy at its minimum for a moving object?

Back

Kinetic Energy is at its minimum when the object's speed is zero.

Front

What factors influence Kinetic Energy?

Back
