A hollow sphere is a three-dimensional object with a spherical shape and an empty or hollow interior. It is similar to a solid sphere, but with a hollow center.
A hollow sphere rolls by converting its potential energy into kinetic energy. As it rolls, the bottom part of the sphere makes contact with the ground, causing it to rotate and gain speed.
Momentum is a measure of an object's motion, and it is defined as the product of an object's mass and its velocity. In simpler terms, it is the quantity of motion an object has.
In the case of a hollow sphere rolling, its momentum is the combination of its linear momentum (due to its translational motion) and its angular momentum (due to its rotational motion).
The rolling momentum of a hollow sphere is affected by its mass, velocity, and radius. Additionally, the surface on which it is rolling and any external forces acting on it can also affect its momentum.
