Physics · Kinematics - Linear and Circular Motion

Which of the following statements with reference to uniform linear motion and uniform circular motion is/are TRUE? 1. In uniform linear motion, a body moves in a fixed direction with constant speed, whereas in uniform circular motion, the speed remains constant but the direction of motion changes continuously. 2. In uniform linear motion, there is an instantaneous change in velocity, whereas in uniform circular motion, the velocity remains completely unchanged. 3. Uniform linear motion is an accelerated motion, whereas uniform circular motion is a non-accelerated motion. Choose the correct answer from the options given below:
