Example Question #1 : Physical Science

Select the example of kinetic energy. 

Possible Answers:

A frisbee before it is thrown

A flowing river

The wheels on a car not being driven 

A stretched rubber band

Correct answer:

A flowing river

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. 

Example Question #2 : Physical Science

Select the example of potential energy. 

Possible Answers:

A car driving down the road

A baseball thrown by a pitcher 

An insect flying 

A stretched rubber band 

Correct answer:

A stretched rubber band 

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.
