What is the work of centripetal forces in uniform circular motion?

Work is equal to Force * displacement * cos(angle between force and displacement). When there is uniform circular motion, the displacement is in the same direction as the velocity: along the tangent of the circle. The centripetal force always points towards the center of the circle. These two directions (vectors) are perpendicular to each other (90 degrees). Cos(90) = 0, so the work is 0.

What happens when centripetal acceleration occurs?
The body which is subjected to centripetal acceleration undergoes uniform circular motion.
Does the centripetal force acting on an object in uniform circular motion do work on the object?
No
Factors that affect tha increase of centripetal force in uniform circular motion?
none
What factors affect the increase of the centripetal force on a particle in uniform circular motion?
Increase in radius affect the increase of the centripetal force on a particle in uniform circular motion. An increase in radius would cause a decrease in the force if velocity remains constant.
What is the origin of centripetal force?
Centripetal force is the resultant force acting towards the centre of orbit of an object undergoing uniform circular motion.
3 What factors affect the increase of the centripetal force on a particle in uniform circular motion?
Speed, friction, momentum, and conservation of motion
What is centripetal acceleration and find its magnitude and direction in the case of uniform circular motion?
The centripetal acceleration is v2/r, directed toward the center of the circle..
Do centripetal forces act by pushing an object towards or away from the center of circular motion?
Towards!
How must the net force depend on the speed of the moving object in order to obtain uniform circular motion?
The force required to keep a body to be in a uniform circular motion is known as centripetal force means centre seeking force. This centripetal force is directly proportional to the square of the speed of the particle.
Is uniform circular motion accelerated?
Yes, it is accelerated. Its acceleration is called centripetal acceleration. Its value is given by: a=v2/R
What two quantities is necessary for uniform circular motion?
The only thing required for an object to show uniform circular motion is a constant centripetal force. The object will have constant speed and kinetic energy, but its velocity, acceleration, momentum, and displacement will change continuously.
What produces the centripetal force for the mass in uniform circular motion?
For the moon, it's gravity. For a yo-yo, it's the tension in the string.
