What does the Law of Conservation of Energy state?

Energy can neither be created nor destroyed. It can only change its form from one type to another.

Energy can be created, just not destroyed. It changes its form from one type to another.

The total energy in our Universe changes, as different forms of energies can be transformed from each other under certain circumstances.

Energy transformations do not passively occur in our lives, rather we actively make use of energies and transform them.

A television works by transforming electrical energy into what other kinds of energy?

Sound, mechanical, and electrical

Light, chemical, and mechanical

What energy transformation occurs when howler monkeys call each other loudly in the forest?

Chemical --> Mechanical --> Sound

Mechanical --> Chemical --> Sound

Energy transformations occur when...

Energy changes from one form to another

Energy is created through conduction

Two forces slide together that are touching

A chemical reaction takes place

List the energy transformations of this object.

Electrical → Mechanical/Sound/Thermal Energy

Electrical → Mechanical/Radiant Energy

Mechanical → Chemical/Thermal Energy

Mechanical → Electrical Energy

Which energy transformation below matches an electrical circuit?

Chemical to heat, sound, light, mechanical

Solar to heat, sound, light, mechanical

If you bounce a tennis ball on the ground, it will bounce back up, but not to the original height from where it was dropped. What is happening to the energy?

When the ball hits the ground, some energy is released as thermal and sound energy, so the kinetic energy bouncing it back up is less.

When the ball hits the ground, some energy is released as chemical and nuclear energy, so the kinetic energy bouncing it back up is less.

When the ball hits the ground, some energy is released as radiant and mechanical energy, so the kinetic energy bouncing it back up is less.

When the ball hits the ground, some energy is released as gravitational and electrical energy, so the kinetic energy bouncing it back up is less.

What is the role of heat in energy transformations?

It is the product of every energy transformation.

It is the catalyst for energy conversion.

It is unrelated to energy transformations.
