Which Will Be First? (Rolling Down an Incline)

The video tutorial explores the problem of determining which object—a hollow sphere, solid sphere, or thin hoop—reaches the bottom of an incline first. It discusses the conservation of mechanical energy, focusing on the conversion of gravitational potential energy to kinetic energy. The tutorial explains how acceleration depends on gravity, incline angle, and rotational inertia. It concludes that the solid sphere, with the smallest rotational inertia fraction, reaches the bottom first, followed by the hollow sphere and thin hoop.
