Homework Statement
A sphere is resting on a horizontal surface. A force parallel to the surface passing through the center of the sphere is applied.
Describe the motion of the sphere
1. Without any friction
2. With friction.
The Attempt at a Solution
When there's no friction, then the motion is purely translatory. But, if there is friction, it will apply a torque which will force rotation as well as translation. The second part isn't right though. Why?
