Eg.1Motion of a freely falling body is an example of uniformly accelerated motion (or motion of a body under the gravitational pull of the earth). (i) The velocity in uniform motion does not depend on the choice of origin. : 1If one travels by a car from one place to another far away place, then length of the car is ignored as compared to distance traveled. As average speed = total pathlength / time interval also, average velocity = Displacement/ time interval . (Scale 5 km/h = 1 cm. For example, a car running at a constant speed of say, 10 meters per second, will cover equal distances of 10 metres every second, so its motion will be uniform.
