Water sitting in a cloud high in the air falls due to gravity, the moving water spins turbines, and they create/store electricity...

Pick the BEST Energy Conversion below for a Hydroelectric Dam.

• Mechanical to Electrical

• Electrical to Mechanical to Thermal

• Potential to Kinetic to Electrical

• Kinetic to Mechanical to Electrical

Making a Fruit Smoothie is YUMMY!
Plug a Blender into the wall outlet, and you're ready to go. 
Which choice below BEST shows the energy transformation of making a smoothie?

• Electrical to Kinetic
• Electrical to Chemical
• Mechanical to Sound
• Kinetic to Thermal

If you drop a basketball, it will bounce, and then roll, and finally stop.
Why won't a basketball bounce forever?

• The ball weighs too much, and that makes it stop.
• Gravity pulls the ball down more than the ball can bounce.
• It's Potential Energy gets destroyed as it bounces.
• It's energy is transformed into other types of energy.

A Steam Locomotive uses wood or coal, to create steam from water. This steam moves pistons, and thus, the train. Choose the best energy transformation below for a steam locomotive.

• Thermal --> Mechanical --> Chemical (plus heat)

• Chemical --> Thermal --> Mechanical (plus heat)

• Mechanical --> Chemical --> Thermal (plus heat)

• Electrical -> Chemical --> Thermal (plus heat)

You have to work to keep a yo-yo going up and down, and up and down. Why does it stop?

• Gravity is too strong and yo-yo is too light.

• Yo-yo's are too heavy for the string.

• Sound and heat are produced, which use up energy.

• Friction energy cancels out the potential energy.
