The law of Conservation of Energy states:

• Energy can be made and destroyed.

• Energy cannot be created or destroyed, it can only be transformed from one form to another.

• Energy cannot be destroyed but can be created and disappear.

• Energy was created by scientists but cannot be destroyed.

. When a ball bounces, it has changing amounts of potential energy and kinetic energy. Eventually, however, the ball will stop bouncing. Why does the ball stop bouncing?

• The ball's energy gets used up during the bouncing motion

• The mass of the ball is probably too small to allow the ball to continue its own motion

• The pull of gravity is stronger than the energy in the ball, which makes the ball slow down.

• The ball's energy gets transformed to other types of energy.

Which statement describes the energy of the pendulum as it moves from Position 1 to Position 5

• As the amount of kinetic energy decreases, the amount of potential energy also decreases, but the total amount of energy remains the same.

• The amount of potential and kinetic energy remains constant during the swing of the pendulum

• The total amount of energy changes during the swing of the pendulum

• As the amount of kinetic energy decreases, the amount of potential energy increases, but the total amount of energy remains the same.

Which of the following groups are examples of chemical energy?

• Wood, food, sun.

• Wood battery, drums

• Batteries, wood, fuel.

• Food, toaster, phone

Which statement below describes how a phone is able to play music after it has been plugged in?

• The electrical energy from the outlet is transformed to chemical energy and then to sound and light energy when the phone is used to play music

• The phone is able to play music because the outlet is creating electrical energy that is transformed to sound energy.

• The electrical energy is transferred from the wall allowing the phone to make sound energy as music

• The phone is able to play music because it is using up the electrical energy from the wall.
