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 = ½(mass) x (velocity)².

Front

What is the formula for calculating Kinetic Energy?

Back

KE = ½(mass) x (velocity)².

Front

What is the unit of Kinetic Energy?

Back

The unit of Kinetic Energy is Joules (J).

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It is often associated with gravitational potential energy.

Front

What is the formula for Gravitational Potential Energy?

Back

Gravitational Potential Energy (PE) = mass x acceleration of gravity x height.

Front

What is the unit of Potential Energy?

Back

The unit of Potential Energy is Joules (J).

Front

What is the unit for Force?

Back

The unit for Force is Newton (N).

Front

What is the relationship between mass and Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object; as mass increases, Kinetic Energy increases.

Front

What is the relationship between velocity and Kinetic Energy?

Back

Kinetic Energy is proportional to the square of the velocity; as velocity increases, Kinetic Energy increases exponentially.
