What is the difference between potential and

kinetic energy?

Potential = Stored energyKinetic = energy in motion

Correct answer: A

Put the points in orderof increasing kinetic

energy:

1, 2, 3, 4(increasing kinetic = least to greatest)

What kind of pulley is picturedabove? How did you know?

Fixed Pulley– the pulley is attached to the ceiling

Moveable Pulley – the pulley moves on the string

Identify the pulley pictured aboveand give an advantage of using this

type of pulley.

It’s a fixed pulley and it changesthe direction that you lift the load

When using a fixed pulley, the amount of force _____ and the

direction the load moves _______.

Force stays the sameDirection the load moves changes

When using a moveable pulley, theamount of force _____ and the

direction the load moves _____.

Force decreases Direction the load moves stays the same

Which pulley system pictured above would require the least amount of

force to lift the load? Explain

Figure 4 – the more pulleys you add,the less amount of force needed
