<h2 dir="ltr">Centripetal Force</h2>
The centripetal force is the force responsible for the object's travel in a circular path. It is always directed toward the center of the circle around which the object travels. If it weren't for this kind of force, the object would travel straight rather than following the curvature.
<h2 dir="ltr">The Formula</h2>
The formula for centripetal force (Fc) is written as,

<h2 dir="ltr">Solved Problems</h2>
Problem 1: A van of 1,250 Kg is traveling at 50. m/s covers a curve of radius 200 m. Calculate the centripetal force.
Solution
Given&nbsp;
mass (m)= 1,250 Kg
radius (r)= 200 m
velocity(v) = 50.0 m/s
By using the centripetal formula,

Problem 2:&nbsp;Suppose a ball that is spinning at the end of a string that you're twirling has a mass of 0.5 kg and is going around with a tangential velocity of 4m/s. Let the length of the string be 2 meters. Find the centripetal force.
Solution:
Given:
m = 0.5 kg
v = 4 m / s
r = 2 m
By using the formula,
