Question

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

Answer 1

uniform linear motion is a motion with a constant velocity,whereas uniform circular motion is the motion with a constant speed.

uniform circular motion where a centripetal acceleration always acts towards the centre and always perpendicular to the velocity of the object.

uniform linear motion is the motion where an object has no acceleration and is travelling with constant velocity.

hope it helps....... 

Answer 2

Answer:

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.
