Kinetic and Potential Energy

Front

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.

Front

What is Potential Energy?

Back

Potential Energy is stored energy that an object has due to its position or condition. For example, a rock at the top of a cliff has gravitational potential energy.

Front

At what point does a diver have the greatest kinetic energy?

Back

At the lowest point of the dive, just before entering the water.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between speed and kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic Energy (KE) = 1/2 * mass (m) * velocity (v)².

Front

What is the formula for calculating potential energy?

Back

Potential Energy (PE) = mass (m) * gravity (g) * height (h).

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has elastic potential energy.

Front

What happens to the total energy of a system when energy transforms from potential to kinetic?

Back

The total energy of the system remains constant; it just changes from one form to another.

Front

What is an example of potential energy?

Back

A book on a shelf has gravitational potential energy due to its height above the ground.
