A small ball is suspended from the ceiling by a thread of negligible mass.
The ball is then set in motion in a horizontal circle so that the thread describes a cone.
The acceleration of gravity is 9.8 m / s 2 .
When an object moves on a circular path with constant speed, its motion is called uniform circular motion.
Even though the object is moving with a uniform speed it is accelerated as its direction keeps on changing.
The acceleration is called centripetal acceleration and it is directed towards the center of the circular path.
The force responsible for the centripetal acceleration is the centripetal force.
It is given by: F c = m v 2/ r
Where:
m = is the mass of the object
v = is the speed of the object
r = is the radius of the circular path
