Displacement when body moves one position to another position,the shortest (straight line)pathlenth distance between initial position to final position of body along with direction is called Displacement. Displacement =velocity × time Displacement uints are meter, centimeter, kilometer etc Displacement is vector Quantity Note .Displacement of moving body can be zero Distance moving body cannot be zero. physics class 9th

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

Distance The distance travelled by body is actual length of path covered by moving body irrespective of direction in which body travels. Distance=Speed×time Distance units are meter, centimeter , kilometer etc Distance is scalar Quantity Physics notes class 9th
