What is electrical energy?

• The energy that an electric current carries. When you plug something in, this energy flows.
• Energy carried in waves of vibrating matter. It cannot travel through empty space (it MUST have matter to travel)
• Energy stored in objects that are compressed or stretched like springs or rubber bands.

Which choice below is most like a pendulum, for demonstrating Potential and Kinetic Energy?

• Roller Coaster

• Kicking a Soccer Ball

• A Water Slide

• A Swing Set

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.

What best describes the energy conversion that occurs when you turn on a hair dryer?

• electric to kinetic to thermal and sound
• chemical to thermal to light and sound
• nuclear to electrical to thermal and sound
• kinetic to light to thermal and sound

What is sound energy?

• The energy that an electric current carries. When you plug something in, this energy flows.
• Energy carried in waves of vibrating matter. It cannot travel through empty space (it MUST have matter to travel)
• Energy stored in objects that are compressed or stretched like springs or rubber bands.
