Enter mass, radius, and velocity to find the magnitude of centripetal force using Centripetal force calculator.
Formula and equation for centripetal force is
Centripetal Force : f = mv2r
Some other formulas derived from the centripetal force equation are
Radius : r = mv2f
Velocity : v = √frm
Centripetal force calculator finds the centripetal force of an object in a circular motion. In other words, it calculates the magnitude of centripetal force. It can also find the centripetal velocity, mass, and radius of an object, if force is given.
If the answer of your calculation is a negative number, it means centrifugal force is acting on the object.
To find centripetal force, you should have the velocity, radius of the circular path, and mass of the object. If you have the angular acceleration of the body, you can still find the magnitude of centripetal force.
Calculate the centripetal force of an object if it is moving in a circle having radius of 5 m, mass of the body is 10 kg, and velocity is 15 m/s.
Place the given values in the equation of centripetal force.
Fc = mv2/r
Fc =10 × (15)2/5
Fc = 450 N
Both are the same but opposite in direction. The centripetal force acts inwardly (pulls the object toward the center) while centrifugal force pushes it away from the center. Both have same formulas. The only difference is, centrifugal force is accompanied by a negative sign.
