Energy Quiz

Q1: ________ is the process of heat moving through direct contact of two objects. A: Conduction

A: The Apple (It’s higher up) Q 2: Which object has MORE Gravitational Potential Energy at it’s current position? A: The Apple (It’s higher up)

Q 3: A windmill generates electric energy by using ______ energy from the moving of it’s blades. A: Mechanical

A: Volume (“loudness”) Q 4: The amplitude of a wave will effect a sound by changing the __________ you hear. A: Volume (“loudness”)

Q 5: When you think of electric energy, it is acceptable to always think of it as: A: Electricity

Q 6: The color you see is controlled by what property of a wave? A: Wavelength

A: Convection (cool air sinks) Q 7: Refrigerators often use _________ to move cool air around to cool the food. A: Convection (cool air sinks)

Q 8: Which form of energy is often made during an energy transfer but is “lost” into the air/space? A: Heat

A: Electric. (Humans don’t “plug in” for electricity) Q 9: What is wrong with the energy flow chart that represents how a human gets their energy? Nuclear Light Chemical Electric Mechanical A: Electric. (Humans don’t “plug in” for electricity)

A: The one with more mass (not necessarily the “larger” one) Q 10: Two marbles sit on a ramp. Which will move the cup more at the bottom? A: The one with more mass (not necessarily the “larger” one)

A: Higher on the ramp! (More height = more GPE!) Q 11: Where would I place the smaller mass marble to accomplish the same amount of energy the larger mass marble will do on the cup? = ? A: Higher on the ramp! (More height = more GPE!)

A: Electric (plugging it in) Q 12: In order to use the mechanical energy in a blender, which form of energy would be helpful to get first? A: Electric (plugging it in)
