Want this question answered?
because there is no force applied on the bucket
roller coaster, when you put water in a bucket and swing the bucket in circles and the water will stay in the bucket
Well, if I am correct the water in the bucket stays in there because of inertia and centripetal force. The water wants to come out of the bucket but inertia prevents the water to come out of the bucket. That is all I know I don't know how centripetal force helps the water stay in the bucket though. Hoped this helped you a bit.
Because the centripetal reaction force of the rotating bucket exceeds the force of gravity attempting to pull the water out.
The force of friction is a contact force. An example of a force at a distance would be gravity.
Make a hole in the bottom center of a bucket, fill the bucket with water, move bucket in a steady circular motion, then let it go...
If the bucket is empty, and sealed so that no water can get in it, then it takes 41.8 pounds (minus the empty weight of the bucket) to completely submerge it.
If it is held stationary, there will be the downward force of gravity, and the upward (normal) force from your hand. The reason that the bucket does not move is because the forces are equal and opposite.
Friction can slow down a rock and the speed of the rock depends on the force you exert.
The question is incomplete. If the bucket is taken in a horizontal plane then no work is done If the bucket is taken in an inclined plane then work has to be done against force of gravity
Bucket is having an angle of deflection of a jet more than 90 degree where as vane is having less than 90 degree. Bucket can generate an IMPULSE FORCE only whereas vane can generate both IMPULSE and REACTION FORCE both. by PRIYANSHU SRIVASTAVA MECHANICAL ENGINEER
