Answer 1

Answer:

SI unit of speed and displacement is m/s

Total path covered iscalled displacement

Starting point is called initial positioni.e u

Simplest type of motion is straight line motion

Distance is measured in odometer in automobiles

Displacement in circular motion is 0 bacause in circular motion v and u r same

DONT UNDERSTAND NEXT QUES

Speed can never be 0 because object in motion will Definitely cover some distance

Yes velocity can be 0 because displacement can be 0
