Questions & Step-by-Step Solutions

If a hollow cylinder rolls down an incline, how does its acceleration compare to that of a solid cylinder?
  • Step 1: Understand what a hollow cylinder and a solid cylinder are. A hollow cylinder is like a tube, while a solid cylinder is filled inside.
  • Step 2: Learn about moment of inertia. This is a measure of how difficult it is to change the motion of an object. A lower moment of inertia means it's easier to roll.
  • Step 3: Compare the moment of inertia of both cylinders. The solid cylinder has a lower moment of inertia than the hollow cylinder.
  • Step 4: Know that when both cylinders roll down an incline, the one with the lower moment of inertia will accelerate faster.
  • Step 5: Conclude that since the solid cylinder has a lower moment of inertia, it will accelerate faster down the incline than the hollow cylinder.
  • Moment of Inertia – The moment of inertia is a measure of an object's resistance to changes in its rotation. A solid cylinder has a lower moment of inertia than a hollow cylinder, affecting their acceleration when rolling.
  • Rolling Motion – Rolling motion involves both translational and rotational motion. The distribution of mass affects how quickly an object accelerates down an incline.
  • Acceleration on Inclines – The acceleration of an object rolling down an incline is influenced by its moment of inertia and the gravitational force acting on it.
