# Single bead on a vertical circle.

• alingy2
However, if the pyramid is spinning at a very high rate, the ball will actually stay at the top.In summary, we discussed a scenario where a bead with a hole in it is passed through a frictionless vertical circle. The bead begins at the bottom and the circle spins around its vertical axis. We then explored the potential outcome if the angular velocity of the circle was very high. While the teacher believes the bead would move higher and follow the shape of the circle, the speaker argues that without any outside forces, the bead would stay at the bottom. They also make a comparison to a ball at the top of a spinning pyramid, where the ball would stay at the top due to the high angular velocity.

Imagine that a single bead has a hole in it. It is passed inside a " vertical " circle with no friction. Imagine that the "vertical"circle moves by spinning around its vertical axis and that the bead is, AT THE BEGINNING, on the bottom of the vertical circle.

We had another problem related to this. However, I am wondering what would happen to the bead if the angular velocity of the vertical circle was very very high.

My teacher says that the bead could higher following the shape of the vertical circle.

However, I think that, as long as there is no perturbation, the ball will stay at the bottom. Is this correct?

I am just starting to get a grasp of Newtonian laws.

Yes, I don't think the bead would move, but that would be a very ideal case. Realistically, it would be shifted one way or another, and then its height determined by the angular velocity of the ring.

Think of a ball at the top of a pyramid. It's in "dynamic equilibrium," where it will technically stay in the same place, but realistically roll down one of the sides.

## 1. What is the single bead on a vertical circle experiment?

The single bead on a vertical circle experiment is a physics experiment that involves a small bead or object moving along a circular track that is oriented vertically. This experiment is used to study the forces acting on the bead and how they affect its motion.

## 2. What are the forces acting on the bead in this experiment?

The forces acting on the bead in this experiment are gravity, tension, and centripetal force. Gravity pulls the bead towards the ground, tension acts on the bead due to the string or track it is attached to, and centripetal force keeps the bead moving in a circular path.

## 3. How is the velocity of the bead affected by the forces?

The velocity of the bead is affected by the forces in different ways. Gravity and tension do not change the speed of the bead, but they do change the direction of its motion. Centripetal force, on the other hand, is responsible for changing the speed of the bead and keeping it moving in a circular path.

## 4. What factors affect the motion of the bead in this experiment?

The motion of the bead is affected by several factors, including the length of the string or track, the mass of the bead, and the speed at which the bead is released. These factors can change the forces acting on the bead and therefore alter its motion.

## 5. What is the purpose of conducting this experiment?

The purpose of conducting this experiment is to study the concepts of circular motion and the forces involved in it. It also helps to understand how these forces affect the motion of an object and how they can be manipulated to control the object's direction and speed.
