RPM
RPM stands for Revolutions Per Minute and measures how many times a rotating object, like a wheel or engine shaft, spins complete circles in one minute. It’s a common way to quantify rotational speed. For example, if a car engine runs at 3,000 RPM, the engine’s crankshaft makes 3,000 full turns every minute. RPM helps assess performance, efficiency, and safety in machinery and vehicles. Higher RPM generally indicates faster rotation, but operating at very high RPM can cause wear and overheating, so it's crucial to stay within recommended limits.
