Force, Motion, and Renewable Energy

Wind power has been beneficial to ranchers, farmers, and rural homeowners for decades. Windmills and turbines use wind power to change the winds kinetic energy into electricity.

Where does the Earth's wind power come from?

• Mechanical Energy

• The water cycle

• Solar radiation

• Solar panels

A dam is built to trap and store water in a reservoir for use to create electricity. Water released from the reservoir flows through tunnels in the dam. The power from the rushing water spins turbines that drive a generator for the production of electricity.

What type of energy was most likely used in this process?

• Hydroelectric energy

• Geothermal energy

• Wind energy

• Solar energy

Which energy source is most likely being described?

• Hydroelectric energy

• Geothermal energy

• Wind energy

• Solar energy

Nigel uses a pool stick to demonstrate how the energy of pushing the pool stick against one ball can cause some of the other balls on the table to display the energy of motion.

Which of the following does not demonstrate a change in energy that causes motion or created changes in other objects?

• A bowling ball running down the lane

• A tennis racket hitting a ball

• A piece of paper in a notebook

• A hot plate heating a pot of water.
