Energy Review

Dropping the ball into which hole will cause the ball to travel the fastest?

• Hole 1, because the ball will have the most potential energy

• Hole 2, because the ball will have the most kinetic energy

• Hole 3, because the ball will have the least potential energy

• Hole 4, because the ball will have the least kinetic energy

Which conclusion is supported by the data?

• The ball had the most energy on roll 1.

• The ball had the least energy on roll 4.

• The ball had less energy on roll 1 than on roll 2.

• The ball had more energy on roll 2 than on roll 3.

Which two ways does the student’s model need to be changed to better show how rainbows are formed?

• The prism should be as high in the air as rainbows are.

• The model needs to be outside because rainbows only form outside.

• The prism should have a round shape because raindrops are round

• The prism should be made of water instead of glass because rain is made of water.

• Sunlight should be used instead of white light because sunlight and white light are made of different things.

Which three explanations support this conclusion?

• More wind energy produced means more pollution.

• Natural gas is a fossil fuel that must be removed from under the ground.

• The largest amount of electricity is produced from nonrenewable resources.

• Getting coal from beneath Earth’s surface destroys the ecosystem in that location

• Solar cells absorb energy that would normally be used by plants to make oxygen.

Which question should the students ask to decide which object to put into Group2?

• How much thermal energy does the object produce?

• How do people use the thermal energy produced by the object?

• Can the object produce thermal energy without being plugged in?

• Can the thermal energy produced by the object be changed into another form of energy?

Based on the data collected, which two conclusions can students make about the speed and energy of the dough when it hit the floor?

• The dough had the fastest speed and the least kinetic energy when dropped from a height of 1 meter.

• The dough had the slowest speed and the most kinetic energy when dropped from a height of 1 meter.

• The dough had more speed and kinetic energy when dropped from a height of 2 meters than from 1 meter.

• The dough had less speed and kinetic energy when dropped from a height of 4 meters than from 3 meters.

• The dough had the fastest speed and the most kinetic energy when dropped from a height of 5 meters.

Why are Friend1’s sounds turned into digital information?

• in case people do not speak clearly

• so the sounds can be sent as radio waves

• so Friend2 can communicate with the tower

• in case the radio waves do not reach Friend2’s cell phone

Students choose playground activities to demonstrate energy transfer.

Which activity shows a transfer of potential energy to kinetic energy?

• sliding from the top of a slide

• hanging from monkey bars

• sitting on a bench

• hiding behind a tree

A girl signals her friend by shining a flashlight on a mirror. Her friend can see the signal because 

• heat energy can be transferred from one object to another

• mechanical energy can be transferred from one object to another

• sound energy can be reflected from one object to another

• light energy can be reflected from one object to another
