Motion is two types 1 uniform motion 2.non uniform motion(accelerated motion) 1.uniform motion whenbody travel equal distance in equal intervals of time is called uniform motion. distance time graph of uniform motion is straight line. Examples car travel 10meter per second. Bus travel 2km per hours.etc 1.non uniform motion whenbody travel equal distance in unequal intervals of time is called uniform motion. distance time graph of non uniform motion is curved line. Examples free falling objects car travel different speed. physics class 9th note
