If you swing a bucket of water fast enough in a vertical circle, at the highest point the water does not spill out. this happens because an outward force balances the pull of gravity on the water.
true or false?

True

Explanation:

If we swing a bucket of water fast enough in a vertical circle the water does not spill out even at the top-most position of the bucket. This happens because the centrifugal force acting away from the center in a circular motion neutralizes or overcomes the gravitational force on the water particles.

Centrifugal force is mathematically related as:

where:

m = mass of the revolving body

r = radius of revolution

angular velocity in radians per second

This force F acts in radially outward direction.

when it gains or loses electrons
