AP Physics 1: Circular Motion

What will happen?

• The object will speed up

• The object will slow down

• The object will change direction

Draw a FBD

• a

• b

• 

• 

Which force (or combination of forces) causes the car to turn (centripetal acceleration)?

• Tension

• Normal Force

• Weight/Force of Gravity

How will the tension change if the cart travels more quickly around the circle?

• It will increase

• It will decrease

• It will stay the same

What would happen to tension if the cart was swung in a horizontal circle and double the speed?

• It would quadruple

• It would double

• It would halve

Which path would the object take? 

• C

• A

• B

• D

• E

What does happen to the required net force towards the center as speed increases?

• It increases

• It decreases

• It remains the same

Predict: What will happen to the speed needed to make it slip if m is increased significantly?

• It will remain the same

• It will increase

• It will decrease

What do you think the tension vs time graph will look like for the vertical plane?

What would the FBD for the water look like?
