Quick answer
Centripetal force F = m x v^2 / r.
F = m v^2 / r

Frequently asked questions
What provides centripetal force?
It can come from tension, gravity, friction or a normal force, depending on the situation.
Why does a car skid on a tight curve?
If required centripetal force exceeds available tire friction, the car cannot follow the curve.
