Centripetal force is the inward force required to keep an object in circular motion. It’s determined by factors like mass, velocity, and radius, following the formula F = (m * v^2) / r. While RPM measures rotational speed, it doesn’t directly affect centripetal force, which relies on these other parameters for calculation.

Topic | Explanation |
---|---|
Centripetal Force | The force required to keep an object moving in a circular path. It acts inward, toward the center. |

What is the relationship between RPM and RCF? Revolutions per minute (RPM) measures rotational speed, while Relative Centrifugal Force (RCF) measures the force experienced by objects in a centrifuge. The relationship is not direct; RCF depends on the rotor radius and RPM.
How much work is done by the centripetal force in one revolution? The centripetal force does no net work on an object undergoing circular motion because it acts perpendicular to the direction of motion. The work done in one revolution is zero.
What is the centripetal acceleration of Earth due to revolution? The centripetal acceleration of Earth due to its revolution around the Sun is approximately 0.006 m/s². It keeps Earth in its elliptical orbit.
