Is RPM dependent on radius? Yes, RPM is indirectly dependent on radius. If the radius (or diameter) of a rotating object changes while the linear speed remains constant, the RPM will also change.

Does velocity increase with diameter? If the linear speed remains constant, the velocity of a rotating object will not change with diameter. However, if the RPM changes due to a change in diameter, the velocity will also change.

What is the formula for pulley speed and diameter? The formula for calculating the speed (RPM) of a pulley using its diameter and the speed of the belt or rope driving it is: RPM = Speed / Pulley Circumference.
