Question

What is the difference between uniform motion in straight line and uniform circular motion?

Answer 1

Uniform Linear motion:

1. An object is said to move in uniform linear motion , if it travels in straight line and covers equal DISTANCE in equal time interval.
2. No change in direction.
3.. SPEED is constant and constant velocity.
4. Acceleration is zero.
Example: A car moving forward at speed of 40km/h towards North direction.

Uniform circular motion:

1. When a body moves in circular path with uniform speed , it's motion is called uniform circular motion.
2. Motion is said to be accelerated.
3. SPEED is constant but direction of motion changes every point.
Example:
An Athelete running in a circular path.
