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 $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?
