Forms of Energy

What is an example of kinetic energy?

• A rolling ball has kinetic energy due to its motion.

• A book resting on a table has kinetic energy.

• A stretched rubber band has kinetic energy.

• A parked car has kinetic energy.

What is energy?

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

• 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.

What type of energy does a bicycle at the top of a hill have?

• Kinetic energy

• Thermal energy

• Potential energy

• Mechanical energy

What is an example of converting energy from one form to another?

• A toaster converts electrical energy into thermal energy.

• A solar panel converts thermal energy into electrical energy.

• A battery converts chemical energy into kinetic energy.

• A wind turbine converts kinetic energy into sound energy.

What is thermal energy?

• Thermal energy is the energy that comes from the temperature of matter.

• Thermal energy is the energy stored in chemical bonds.

• Thermal energy is the energy associated with the motion of electrons.

• Thermal energy is the energy released during nuclear reactions.

Which has more energy: a ball on the ground or a ball high in the air?

• A ball on the ground has more energy.

• Both balls have the same amount of energy.

• A ball high in the air has more energy.

• A ball on the ground has no energy.

What is sound energy?

• Sound energy is the energy produced by vibrating sound waves.

• Sound energy is the energy produced by moving air particles.

• Sound energy is the energy stored in musical instruments.

• Sound energy is the energy that can be converted into light.

What is potential energy?

• The energy of an object in motion.

• The energy stored in an object due to its position or state.

• The energy released during a chemical reaction.

• The energy required to change the temperature of an object.

How do you calculate total mechanical energy?

• By subtracting potential energy from kinetic energy.

• By adding potential energy and kinetic energy together.

• By multiplying potential energy by kinetic energy.

• By dividing kinetic energy by potential energy.

What is the Law of Conservation of Energy?

• Energy can be created and destroyed.

• Energy can be converted from one form to another, but cannot be created or destroyed.

• Energy is always constant and cannot change forms.

• Energy can only be stored, not converted.
