Circular Circular motion Motion Water

In summary, when a bucket filled with water is in vertical circular motion, there exists a contact force between the water and the bucket at the top of the center of rotation. This is because the bucket is accelerating downwards at more than 1g, providing a centripetal force to constrain the water to move in a circular path. If the bottom part of the bucket is removed while at the top, the water will leave through the bottom and travel on a tangential path, as if any mass were being swung on a string in a vertical plane. The contact force will be at least twice the weight of the water if the rotation is uniform. When doing a force balance on the water in the bucket, the equation R+mg=mv

Yes Thank you for modelling my query as a formal physics question.

Related to Circular motion of a bucket filled with water

1. What is circular motion?

Circular motion is the movement of an object along a circular path. It involves a continuous change in direction, but the speed of the object remains constant.

2. How does a bucket filled with water move in circular motion?

A bucket filled with water will move in circular motion if it is swung around in a circular path. The water inside the bucket will also move in a circular path due to the centrifugal force created by the rotation.

3. What is the role of centrifugal force in circular motion of a bucket filled with water?

Centrifugal force is the outward force that acts on an object moving in a circular path. In the case of a bucket filled with water, the centrifugal force is responsible for keeping the water in the bucket as it moves in a circular motion.

4. How does the speed of the bucket affect the circular motion of the water inside?

The speed of the bucket affects the circular motion of the water inside in two ways. Firstly, a higher speed will create a stronger centrifugal force, causing the water to move in a wider circular path. Secondly, a higher speed will also cause the water to rise up the sides of the bucket due to the inertia of the water.

5. What happens to the water inside the bucket when the circular motion stops?

When the circular motion stops, the centrifugal force acting on the water also stops. This causes the water to move in a straight line, resulting in the water spilling out of the bucket. The water will continue to move in a straight line until it is affected by another force, such as gravity.
