Energy, Work, and Power

What is the unit of power?

• Joule (J)

• Watt (W)

• Volt (V)

• Ampere (A)

What is kinetic energy?

• Kinetic energy is the energy of an object in motion.

• Kinetic energy is the energy stored in an object at rest.

• Kinetic energy is the energy released during a chemical reaction.

• Kinetic energy is the energy associated with an object's temperature.

What is the formula for calculating work?

• Work = Force + Distance

• Work = Force x Distance

• Work = Force / Distance

• Work = Distance - Force

Which two letters represent objects with the most kinetic energy?

• A & B

• X & Z

• C & D

• E & F

Can energy be created or destroyed?

• Yes, energy can be created and destroyed.

• Energy can only be created, not destroyed.

• No, energy cannot be created or destroyed; it can only be transformed from one form to another.

• Energy can be destroyed but not created.

What is the unit of energy?

• Watt (W)

What happens to potential energy as an object falls?

• It increases while kinetic energy decreases.

• It remains constant throughout the fall.

• It decreases while kinetic energy increases.

• It becomes negative as the object falls.

What is energy?

• Energy is the ability to cause change or do work.

• Energy is a measure of the amount of matter in an object.

• Energy is the force that opposes motion.

• Energy is the speed at which an object moves.
