Answer: Centripetal
Explanation: The centripetal force refers to the acting on a body moving in a circular path. This force acts in the direction of the center of rotation. The centripetal force is given by :
F = mv^2 / r
Where m = mass of th body
v. = Velocity
r = radius of the circular path.
For an object to move in a circular path, the force required is called the centripetal force. It is measured in Kgms^-2. It is directly proportional to the product of the Mass and square of it Velocity and varies inversely to the Radius of its path.
