Questions 1 - 4
1

Select the example of kinetic energy.

A flowing river

A stretched rubber band

The wheels on a car not being driven

A frisbee before it is thrown

Explanation

There are two types of energy: potential and kinetic.

Potential energy is stored energy.

Kinetic energy is energy that is in motion.

We are looking for the option that is in motion:

A stretched rubber band is not in motion; thus, this is not the correct answer.

The wheels on a car that isn't being driven are not in motion; thus, this is not the correct answer.

A frisbee before it is thrown is not in motion; thus, this is not the correct answer.

A flowing river is in motion; thus, this is the correct answer.

2

Select the example of potential energy.

A stretched rubber band

A baseball thrown by a pitcher

An insect flying

A car driving down the road

Explanation

There are two types of energy: potential and kinetic.

Potential energy is stored energy.

Kinetic energy is energy that is in motion.

We are looking for the option that is not in motion:

A baseball being thrown is in motion; thus, this is not the correct answer.

An insect flying is in motion; thus, this is not the correct answer.

A car driving down the road is in motion; thus this is not the correct answer.

A stretched rubber band is not moving, it's in waiting. Once a stretched rubber band is let go, it will likely fly across the room. But as it's just stretched, it has potential energy.

3

What type of energy is in motion?

Potential Energy

Kinetic Energy

Both choices are correct

Neither choice is correct

Explanation

There are two types of energy: potential and kinetic.

Potential energy is stored energy.

Kinetic energy is energy that is in motion.

The correct answer is kinetic energy.

4

Kinetic Energy

Both choices are correct

Neither choice is correct

Explanation

There are two types of energy: potential and kinetic.

Potential energy is stored energy.

Kinetic energy is energy that is in motion.

The correct answer is potential energy.
