An object travels in a circle at constant speed as shown in the animation.  You can change R and T and then view the results using the "Start Animation" link.

1.  Which arrow represents the direction of the acceleration?

2.  Which arrow represents the direction of the velocity?

3.  What happens to the acceleration if you keep R the same but increase the speed, v?  (Hint:  Consider how you can increase v by changing T?)

4.  What happens to the acceleration if you keep T the same but increase the radius, R?
