Question

difference B/W uniform curcular and linear 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.

Answer 2

linear says motion in a straight line and circular says motion in a one revolutionary circle
