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 the speed at which it is moving.

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 the height of an object above the ground.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy depends on two factors: mass and speed. The formula is KE = 1/2 mv², where m is mass and v is speed.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the potential energy held by an object because of its height above the ground. It is calculated using the formula PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

How does height affect Potential Energy?

Back

The higher an object is, the greater its potential energy. This is because potential energy increases with height.

Front

What happens to Potential Energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, but the total mechanical energy remains constant.

Front

At which point does a pendulum have maximum Potential Energy?

Back

A pendulum has maximum potential energy at its highest point (the endpoints of its swing).

Front

What is the relationship between Potential Energy and Kinetic Energy?

Back

Potential Energy can be converted into Kinetic Energy and vice versa, but the total energy in a closed system remains constant.

Front

What is the formula for calculating Potential Energy?

Back

The formula for Potential Energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the effect of mass on Kinetic Energy?

Back

Increasing the mass of an object increases its kinetic energy if the speed remains constant.
