Rubio CFA 3 Review

__________ is stored energy. 

• Potential
• Kinetic
• None of the above 
• All of the above 

At which point is potential energy greatest and kinetic energy the least?

• W
• X
• Y
• Z

Answer explanation

The highest point will have the maximum potential energy and minimum kinetic energy.

At which point is kinetic energy greatest? 

• W
• X
• Y
• Z

Answer explanation

The greatest kinetic energy will always be at the lowest point.

When a roller coaster is at the top of a hill it has

• high potential energy

• high kinetic energy

• low potential energy

• equal amounts of kinetic and potential energy

Which passenger has the most potential energy?

• A

• B

• C

• D

At what position does the rock have the greatest kinetic energy?

• A
• B
• D
• E

What is happening from A to C?

• Kinetic energy is decreasing

• Kinetic energy is increasing

• Potential energy is decreasing

• Potential energy is increasing

Answer explanation

If it's moving up then potential energy is going up.

If passenger A is 8 meters high and decides to jump off, at what point would potential and kinetic energy be equal?

• 7 meters

• 4 meters

• 2 meter

• 6 meters

Answer explanation

Potential and kinetic energy will always be equal in the middle or half way point.
