Unit 2: Week 1 8th Grade Potential vs Kinetic Energy

What is potential energy?

• The amount of energy an object could have if it tried hard enough.

• Moving energy

• Stored energy

• Active energy

What is kinetic energy?

• Stored energy

• Moving energy

• Potential energy

• All of the above

When a ball rolls down hill, its potential energy _____________ and its kinetic energy ______________.

• increases, increases

• increases, decreases

• decreases, decreases

• decreases, increases

The faster an object moves, the ________ kinetic energy it has. 

• more
• less
• none of the above
• all of the above 

Where would this tossed baseball have the least amount of kinetic energy?

• point y

• point z

• Kinetic Energy

• Potential Energy

• Both

• Neither

Which ball has the greater potential energy and why?

• The blue ball has more PE because it is closer to the ground.

• The blue ball has more PE because it has more mass.

• The green ball has more PE because it's height is greater.

• The green ball has more PE because it has less mass.
