In the Laboratory, a Solid Cylinder Is Permitted to Roll $\omega$

question 32

Multiple Choice

In the laboratory, a solid cylinder is permitted to roll down a plane inclined at an angle with the horizontal. If no slipping occurs, which of the following is true?

• A) No slipping implies no frictional force to consider.
• B) Because there is no slipping, the motion of the cylinder can be considered to be a pure rotation about the center of mass.
• C) The change in potential energy is equal to I₀\(\omega\)².
• D) The acceleration of the center of mass can be expressed in terms of the acceleration due to gravity and \(\theta\).
• E) The only force acting on the cylinder is that of gravity.
