Explain centripetal force? Think about the difference between uniform and non-uniform circular motion, examples and work done? If a ball of mass 0.5kg does a uniform horizontal circular motion of radius 5.0cm. If the velocity of the mass is 2.0 m/s what will be the tension force, centripetal force and period and frequency?
Homework Answers
Centripetal force: A centripetal keeps the object move in
circular object and defined as the force that acts on a
body moving in a circular path and is directed towards the center
around which the body is moving.
A uniform circular motion is circular motion of object with a
constant speed and a non uniform circular motion is the motion is
circle with a speed which changes with time.
Given,
mass m=0.5kg, r=5cm=0.005m, v=2m/s
Here the tension force and centripetal force will be same because
no specific location is given( like when the object is on the top
or at the bottom)
So, Tension or centripetal force is : 
T=400 N
Period of the object is given by: 
Frequency of the object is given by:
