Momentum is a measure of an accelerating force over a period of time. It is measured by the product of mass and velocity.
p = mv (kg ms-1)

Momentum is a vector quantity, as it also indicates direction. The definition of momentum also shows that:…

Because the object is traveling in a circle, its velocity is constantly changing. This means is it accelerating. According to Newton's first law, for an object to accelerate, it must have a resultant force applied to it. This
resultant force is known as centripetal force.
F = mvr
