circular motion
center accepting
center seeking
center fleeing

A car is doing donuts in a parking lot. It completes 5 circles in 35 seconds. What is the period of rotation, in seconds?
A pig is flying in uniform circles with a period of 2 seconds. How many circles does the pig complete over ten seconds?
Two riders sit at positions X and Y. Do they have different periods of rotation and why / why not?
No, because they have the same tangential velocity.
No, because they take the same amount of time to complete 1 loop.
Yes, because they have different tangential velocities.
Yes, because they have different masses probably.
Two riders sit at positions X and Y. With every loop, do they travel the same distance?
Yes, since they are on the same ride
No, rider Y travels a greater circumference
A runner is running around a circular track. The track has a diameter of 15 meters. How many meters, in total, does the runner run when it completes one loop?
Depends on how long it takes him to run the loop
47.12 meters
94.25 meters
176.71 meters
This car is (a) and also turning (b)
An object is traveling in a conical pendulum, as shown. What measurements would the student need in order to calculate the tangential velocity?
Radius only
Radius & period
Radius, period, and mass of the object
Radius, period, and length of the string
What force, or component of force, is equal to the net centripetal force?
The horizontal tension component
The vertical tension component
The force of gravity
The velocity force
