Energy transformations occur when...
energy is created through conduction
energy changes from one form to another
energy is destroyed through fusion
energy is initially created then it is destroyed
The Law of Conservation of Energy states -
Energy can be created, just not destroyed. It changes its form from one type to another.
Energy can not be created nor destroyed. It can only change from one form to another.
The total energy in our universe constantly 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 energies.
Which statement best defines mechanical energy?
Energy produced by a machine or moving parts.
Energy that is produced by an electrical current in a circuit.
Energy from the sun.
Energy that travels in waves due to vibrations.

When water falls through a dam and turns a turbine connected to a generator, electricity is produced. This electricity is often used to light our homes and offices. Which of the following shows the energy transformations that occurs?
electrical → light → mechanical
chemical → mechanical → electrical
mechanical → chemical → light
mechanical → electrical → light
Electrical → Mechanical → Sound
Which device were the students most likely observing?
The picture shows a light bulb attached to a hand generator. What energy transformation occurs as the handle of the generator is turned?
thermal → solar → light
solar → light → electrical
mechanical → electrical → light
electrical → mechanical → light
The diagram shows a circuit with bulbs glowing. How does the energy change as it moves from inside the battery, along the wires, and through the light bulb?
electrical → light → chemical
light → electrical → chemical
chemical → electrical → light
chemical → light → electrical
Fusion reactions power the Sun and other stars. In a fusion reaction, two light nuclei merge to form a single heavier nucleus. The process releases lots of energy. What kind of reaction is this?
chemical
nuclear
electromagnetic
magnetic
