What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and its velocity.

What is the formula for calculating Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the standard unit of Kinetic Energy?

Back

The standard unit of Kinetic Energy is the Joule (J).

Front

How does mass affect Kinetic Energy?

Back

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

Front

How does velocity affect Kinetic Energy?

Back

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

Front

What is the relationship between Kinetic Energy and work?

Back

Work done on an object is equal to the change in its Kinetic Energy.

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.

What is momentum?

Back

Momentum is the quantity of motion an object has, calculated as the product of its mass and velocity (p = mv).

How is Kinetic Energy related to momentum?

Back

Kinetic Energy can be expressed in terms of momentum: KE = p²/(2m), where p is momentum and m is mass.

What is potential energy?

Back

Potential Energy is the stored energy of an object due to its position or state, which can be converted to Kinetic Energy.
