as we know that centripetal force is right angke to the displacement, so workdone by it is given as
W = F d cos (90)
W = 0 J
so workdone by the force is zero.

Consider an object in uniform circular motion. A.) If the trajectory and the mass of the object are unchanged, but the centripetal force is doubled, is the object's speed multiplied by a factor of 1, square root of 2, 2, or 4? B.) If the mass of the object is halved and the radius of the circle quadrupled, while keeping the mass of the object the same, is the object's speed multiplied by a factor of1, square root of 2,...
A small coin of mass m1 is undergoing a uniform circular motion at a velocity v. The radius of the circular path is r. A piece of putty of mass m2 is dropped onto the coin. The new velocity of the coin-putty system is a. v b. m1v/m2 c. m2v/m1 d. m1v/(m1 +m2) e. m2v/(m1 +m2)
Objective: In this lab the Centripetal force required to maintain an object in uniform circular motion will be measured. The relationship between a rotating object's mass, velocity, and distance from the center of rotation to the centripetal force will be tested against theoretical expectations. Equipment: Centripetal Force Apparatus with 1, 2, 4oz weights, Force sensor, Magnetic field sensor, Short lab stand with cross bar, 500 g&1kg counter weights, scissors jack, "C" clamp Background: When an object is in uniform circular motion...
The acceleration vector of a particle in uniform circular motion a) points outward from the center of the circle. b) points toward the center of the circle. c) is zero. d) points along the circular path of the particle and opposite the direction of motion. e) points along the circular path of the particle and in the direction of motion.
A small car weighing 588.0 N is in uniform circular motion along a vertical circle. At the highest point of the ride, the car experiences a normal force of magnitude 528.0 N. What is the normal force the car experiences at the bottom of the circle?
