Question

difference between uniform motion and uniform speed ??

Answer 1

Uniform Motion is defined as the type of motion in which the speedof the body moving in a straight line ( i.e. velocity) remains unchanged over a period of time. ... Constant speed means covering equal distances in equal intervals of time by body moving along any path (straight , curved or circular).

Answer 2

Uniform motion means uniform speed in a constant direction i.e. constant velocity but uniform speed alone might be in changing directions also for e.g. uniform circular motion where speed remains uniform but direction keeps on changing at every instant.
