Energy Change and Conservation

This is what happens during an energy transformation, what is it?

• Energy is lost
• Energy is created
• Energy changes from one form to another
• Energy does not change

Which is a common energy transformation?

• Potential to kinetic
• Kinetic to thermal
• Light to sound
• Chemical to mechanical

Which is proportional to Gravitational potential energy?

• Speed and mass
• Temperature and pressure
• Volume and density
• Weight and height above the ground

When sound waves pass through matter what happens?

• It disappears
• It moves temporarily and returns to its normal position
• It travels in the direction of the wave
• It converts to energy

When a pendulum is at its highest, its kinetic energy is what?

• It is at its maximum
• It is increasing
• It is zero
• It is equal to potential energy

Energy transformation is....

• The movement of energy from one object to another
• The change of energy from one form to another
• The creation of energy from nothing
• The storage of energy in one place

Sound waves are...

• A form of energy that moves matter
• A type of kinetic energy
• Energy that can be stored
• Vibrations that allow us to hear

The law of conservation of energy says....

• Energy can be created and destroyed
• Energy can change forms but cannot be created or destroyed
• Energy is always lost in transformations
• Energy cannot move from one place to another

What happens to the energy of a pendulum that swings up?

• It gains potential energy and loses kinetic energy
• It gains kinetic energy and loses potential energy
• It remains constant
• It is transformed into sound energy

Energy moves a certain way in sound waves....how does it move?

• By transporting matter to a new location
• By creating a vacuum
• By passing through matter without moving it
• By altering the chemical composition of matter
