THE PRACTICE STUDIO
Go slowly. Ask why. Make it yours.
PRACTICE / Centripetal acceleration
A shorter lap changes the acceleration
An object moves on the same circle, but its period is reduced from 4 s to 2 s.
Find the ratio of new radial acceleration to old radial acceleration.
Organize the givens & assumptions
- Told = 4 s
- Tnew = 2 s
- r unchanged
Same radius before and after; each compared motion is uniform around the circle.
- A
- B
- C
- D
