## Centripetal force formula

The force that acts on an object moving in a circular orbit and heads toward the centre where the object moves is called centripetal force.

When an object moves in a circular orbit at a constant velocity, the centripetal force accelerates toward the centre.

### The formula for centripetal force is

**F _{c} = mv^{2} / r**

Where

F_{c} = centripetal force

M= mass

V= velocity

R= radius of the path

## Solved examples

**A small van weighing 1,250 kg travels on a curve with a radius of 200 m at 50.0 m / s. Calculate centripetal force.**

Given parameters

Mass = 1,250kg

Radius = 200m

Velocity = 50.0 m / s

Substitute the value of the given equation

Centripetal force

F_{c} = mv^{2} / r

F_{c} = (1250) (50^{2}) / 200

F_{c} = 15.625 N
