Inclined Planes and the Order of Objects Reaching the Bottom

What is an inclined plane and how does it affect the movement of objects?

When a disk, a hoop, and a solid sphere are released at the same time at the top of an inclined plane, in what order do they reach the bottom?

Explanation:

An inclined plane is a simple machine that consists of a sloping surface that allows an object to be moved from a lower point to a higher point with less force than would be required to lift the object directly. The inclined plane reduces the amount of work required by increasing the distance over which the force is applied.

When a disk, a hoop, and a solid sphere are released at the same time at the top of an inclined plane and they all roll without slipping, they will reach the bottom in the following order: solid sphere, disk, hoop.

The mechanical advantage of an inclined plane is determined by the ratio of the length of the incline to its height. The longer the incline, the less force is required to move the object, but the longer the distance over which the force must be applied. The height of the incline also affects the mechanical advantage, with a steeper incline requiring less distance to cover but more force to move the object.
