Potential & Kinetic Energy Review

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass of the object and the square of its velocity.

Front

What is the formula for calculating Kinetic Energy?

Back

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

Front

What type of energy does a stretched rubber band represent?

Back

Potential Energy.

Front

At which point of a roller coaster is potential energy the greatest?

Back

At the highest point of the roller coaster.

Front

What is the relationship between Potential Energy and Kinetic Energy?

Back

They have an inverse relationship; as one increases, the other decreases.

Front

How much kinetic energy does a moving 6 kg object have if it moves with a velocity of 3 m/s?

Back

27 J.

Front

What happens to the potential energy of an object as it falls?

Back

As it falls, its potential energy decreases while its kinetic energy increases.

Front

What is gravitational potential energy?

Back

Gravitational Potential Energy is the potential energy an object has due to its height above the ground, calculated as PE = mass (m) * gravity (g) * height (h).

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and its velocity.
