🌀Centripetal Force Calculator
Enter any 3 of force, mass, speed, and radius — the fourth is solved instantly.
Free Centripetal Force Calculator
Working through a circular motion problem? Our free centripetal force calculator solves F = mv²/r instantly. Enter mass, speed, and radius, and get the centripetal force and acceleration immediately — or work backwards to find the missing variable from the other two.
Don't have linear speed? Enter the period, frequency, or angular velocity instead, and the calculator converts it automatically. A live animated diagram shows the object moving in its circular path with the force vector pointing toward the center.
Whether you're studying circular motion for a physics class or checking an orbital mechanics calculation, this tool gives accurate answers with the reasoning shown. No sign-up, no downloads, no limits.
