Kinetic & Potential Energy Review

Front

What is the Law of Conservation of Energy?

Back

Energy cannot be created or destroyed, only transferred from one form to another.

Front

How do you calculate kinetic energy?

Back

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

Front

What is gravitational potential energy?

Back

The energy an object possesses due to its position in a gravitational field.

Front

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

Back

At the highest point of the roller coaster.

Front

What is weight?

Back

The measurement of the force of gravity acting on an object.

Front

When does an object have no kinetic energy?

Back

When it is at rest.

Front

What is the formula for calculating potential energy?

Back

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

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on position.

Front

What happens to potential energy as an object falls?

Back

Potential energy decreases while kinetic energy increases.

Front

What is the unit of energy?

Back

The unit of energy is the Joule (J).
