Answer 1

uniform linear motion means speed of body is constant during motion
but non uniform linear motion means speed of body doesn't remain constant during motion

Answer 2

Answer:

Uniform linear motion is uniform motion along a linear path or a straight line. The direction of motion is fixed. So, it is not accelerated. For e.g.: a car running with uniform speed of 10km/hr on a straight road.  

Uniform circular motion is uniform motion along a circular path. The direction of motion changes continuously. So, it is accelerated. For e.g.: motion of earth around the sun.
