8th EXAM - 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 the stored energy of an object due to its position or state. It is often associated with the height of an object above the ground.

Front

Which type of energy does a moving car have?

Back

Kinetic Energy.

Front

Which type of energy does a book on a shelf have?

Back

Potential Energy.

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 factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy depends on the height and mass of the object.

Front

What is the Law of Conservation of Energy?

Back

Energy cannot be created nor destroyed; it can only be transformed from one form to another.

Front

Give an example of Kinetic Energy in everyday life.

Back

A tennis ball rolling across the court.

Front

Give an example of Potential Energy in everyday life.

Back

A boulder resting on a hill.
