Understanding Kinetic Energy

What type of energy is demonstrated when a robot moves?

• Sound energy

• Potential energy

• Thermal energy

• Mechanical energy

Why is thermal energy considered a form of kinetic energy?

• Because it is stored energy

• Because it involves the movement of electrons

• Because it is visible to the human eye

• Because it results from fast-moving atoms and molecules

What happens to electrical energy when you turn off a device?

• The electrons stop flowing

• The electrons move faster

• The energy is stored as potential energy

• The energy is converted to sound

How does sound energy travel?

• By reflecting off surfaces

• In a straight line

• Through vibrations in waves

• By heating the air

Which type of radiant energy is visible to the human eye?

• Radio waves

• Gamma rays

• X-rays

• Light energy
