Centripetal Force Calculator

Calculate Circular Motion Parameters

Calculate centripetal force, acceleration, angular velocity, and period for objects in circular motion using F = mv²/r.

Motion Parameters

kg
m/s

Tangential velocity

m

Radius of circular path

Formulas

F = mv²/r

a = v²/r

ω = v/r

Note

Centripetal force always points toward the center of the circular path and is perpendicular to velocity.

About Centripetal Force

Centripetal force is the force that keeps an object moving in a circular path. It always points toward the center of the circle.

  • Always directed toward center
  • Perpendicular to velocity
  • Changes direction, not speed

Real-World Examples

  • Car turning on a curved road
  • Satellite orbiting Earth
  • Ball on a string being swung
  • Roller coaster loop
  • Electrons orbiting nucleus
