Potential & Kinetic Energy Review

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its speed.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the edge of a cliff has potential energy.

Front

How can you increase kinetic energy?

Back

You can increase kinetic energy by moving faster or increasing the mass of the object.

Front

What does the Law of Conservation of Energy state?

Back

The Law of Conservation of Energy states that energy cannot be created nor destroyed, only transformed from one form to another.

Front

At what point is potential energy greatest in a swinging pendulum?

Back

Potential energy is greatest at the highest point of the swing.

Front

What type of energy does a basketball have when held in a player's hands?

Back

The basketball has potential energy when held in a player's hands.

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 formula for kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for 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

Can energy be created or destroyed?

Back

No, according to the Law of Conservation of Energy, energy cannot be created or destroyed.
