Which of the following is an example of uniform circular motion? </br>(a) a car accelerating on a straight road </br>(b) a pendulum swinging back and forth </br>(c) a satellite orbiting the earth at a constant altitude </br>(d) a ball rolling down a hill

(c) a satellite orbiting the earth at a constant altitude Reason — A satellite orbiting the Earth at a constant altitude experiences uniform circular motion because it maintains a constant speed while continuously moving along a circular path around the Earth. The car moving along a straight path and may be changing its speed, but it is not following a circular path. A pendulum exhibits periodic motion as it swings back and forth due to gravity but it is not circular motion. The ball is rolling along a sloped path, not a circular one.
