A particle object undergoes uniform circular motion at a speed v around a circle of radius r. Given v and r, the magnitude of centripetal acceleration is a0. Assume when either v or r are changed, the particle remains in uniform circular motion. 1. Suppose the radius of the circle is cut in half. What happens to the magnitude of the centripetal acceleration? choices: the acceleration doubles, acceleration increases by square root of 2, acceleration remains the same, acceleration decreases...

1.) You whirl a stone in a horizontal circle in such a way that the stone is in uniform circular motion. Which of the following is true for this situation? (Select all that apply.) The change in direction of the stone's motion is due to the centripetal force acting on the stone. The direction of the stone's velocity changes as it moves around the circle. The stone is moving with constant velocity. The stone's speed is constant. The magnitude of...

A toy car of mass 200 g is moving on a circular path of radius 20 cm at a constant speed v. It takes 8 s to complete one circle. What is the centripetal force, acting on the car? The answer is .024 N, I am only interested in the explanation of the problem. (if its just formulas its fine, just name each variable)
