- Q1While camping, Mike wanted to build a fire to keep warm. After collecting wood, he lit a match to start the fire. What type of energy change happened when the wood caught fire?from mechanical to kinetic and heatfrom chemical to light and heatfrom chemical to potential and heatfrom mechanical to chemical and heat30sEditDelete
- Q2A toy robot runs on batteries and is operated by a remote control. The robot is made to walk in a circle and then talk. What type of energy transformations occur during this process?nuclear energy to kinetic energy to sound energykinetic energy to heat energy to sound energychemical potential energy to kinetic energy to sound energythermal energy to potential energy to sound energy30sEditDelete
- Q3In an effort to reduce a school's environmental impact, a school board is planning to install solar panels on the roof to collect sunlight. What is the energy conversion performed by these panels?Electrical energy is converted into sound energy.Light energy is converted into electrical energy.Sound energy is converted into electrical energyHeat energy is converted into light energy.30sEditDelete
- Q4Tori rubs her hands together quickly on a winter evening. Why does rubbing hands together help warm them?Heat is absorbed from the air by the hands.Heat is conducted between two hands when they are touching.Heat is transferred back and forth between two hands when they are close together.Heat is generated by friction between the hands.30sEditDelete
- Q5Lauren pushes a book off the edge of a table. Which energy change occurs as the book falls from the table?potential to kineticmechanical to electricalelectrical to mechanicalkinetic to potential30sEditDelete
- Q6Juan's room is suddenly dark when an incandescent light bulb burns out. He attempts to replace the old bulb with a new one, but realizes that the old bulb is too hot to touch. Juan waits 10 minutes and then changes the bulb when it is completely cool. What happened to the heat in the bulb?The heat was transformed into electricity.The heat was completely destroyed.The heat was stored as chemical energy.The heat was transferred to the air around it.30sEditDelete
- Q7To demonstrate the Law of Conservation of Energy, a student riding a bicycle uses the brakes to slow and stop the bike. He concluded that friction caused the bicycle to stop. Which energy transfer explains why the bicycle stopped?Friction between the bicycle's brake pads and the moving wheels caused mechanical energy to be transformed into thermal energy.Friction between the bicycle's pedals and the moving wheels caused mechanical energy to be transformed into thermal energy.Friction between the bicycle's brake pads and the moving wheels caused kinetic energy to be transformed into potential energy.Friction between the bicycle's pedals and the moving wheels caused kinetic energy to be transformed into potential energy.30sEditDelete
- Q8Which is true of every energy transformation?Energy is conserved.Energy is destroyed.Matter is formed.Energy is created.30sEditDelete
- Q9Some of the energy put into tossing a basketball is lost FROM THE BALL while it is moving through the air. What force causes this energy loss?frictioninertiaheatmomentum30sEditDelete
- Q10Which is an example of evidence that energy is neither created nor lost during a transformation?If you drop a tennis ball, the tennis ball will never stop bouncing.Ice does not melt in the hot sun.Ice melts in the hot sun.When a driver of a car applies the car's breaks, friction heats the breaks.30sEditDelete
