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
