Question

Write the difference between uniform translational motion and uniform circular motion.

Answer 1

Sr. No.	Uniform translational motion	Uniform circular motion
1.	The direction of motion remains completely constant along a straight-line path.	The direction of motion changes continuously at every point along the curved path.
2.	The velocity is constant because both speed and direction do not change.	The velocity is variable because the direction of motion changes continuously.
3.	The magnitude of speed remains constant throughout the entire motion.	The magnitude of speed remains constant throughout the entire motion.
4.	The acceleration is zero because there is no change in velocity.	The acceleration is non-zero and acts towards the center as centripetal acceleration.
5.	The net external force acting on the object is zero.	The net external force is non-zero and acts as a centripetal force.
