What Is Centripetal Force?
Centripetal force is the force directed toward the center that keeps an object moving in a circular path on its orbit.
How is it calculated?
How Is It Calculated?
Fc = m × v² ÷ r
- Enter the mass, velocity and radius.
- The square of the velocity is multiplied by the mass and divided by the radius.
Frequently Asked Questions
Does the force increase when the radius decreases?
Yes; at the same velocity, the required centripetal force increases as the radius decreases.
