AP Physics 1: Circular Motion

What will happen?

• The object will speed up

• The object will slow down

• The object will change direction

What will happen?

• It will speed up.

• It will slow down.

• It will change direction.

What will happen?

• It will speed up.

• It will slow down.

• It will change directions.

Which is not part of Uniform Circular Motion?

• The radius is constant.

• The velocity is constant.

• The speed is constant.

• The object move along a circular path.

Which statement is false?

• A projectile undergoes uniform circular motion.

• A projectile follows a parabolic path.

Which statement is false?

• A centripetal force is a new type of force.

• The centripetal force could be a combination of forces.

• Centripetal force is just a description of a job a force or forces do/does.

Draw a FBD

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
