Question
You swing a bucket of water attached to a string in a circle above your head. What keeps the water in the bucket?
- Acceleration
- Velocity
- Centripetal acceleration
- Centrifugal acceleration
Hint:
a centrifugal force acts on the rotating body
The correct answer is: Centrifugal acceleration
Arm exerts a force to turn the bucket - which is the centripetal force. a centrifugal force acts on the rotating body which pins the water to the bucket( quite like in a car). now if the centrifugal force is greater than the force of gravity. your water will remain in the bucket when it's above your head.
The force created by the circular swinging motion mimics that of gravity, which is what keeps the water in the bucket in the first place.
