PHYSICS
1. Motion is relative or absolute? Give reason.
2. Name the physical quantity that essentially changes as a body moves.
3. Is displacement or distance independent of path? How?
4. Give example of a motion in which distance is covered but there is no displacement.
5. Give one example of motion where, distance and displacement are same.
6. When moving car returns to the same point what will be the ratio of a) Displacement to distance. b) Distance to displacement.
7. In a long distance race, the athletes take four rounds of a track such that the time of Finish is same as the line of start. The length of the track is 200 m. a) What is the total distance covered by the athletes? b) What is the displacement when they touch the finish line? c) Is the motion uniform or non-uniform? d) Is the displacement and distance moved by the athletes at the end of the race equal? Why?
8. A man walks 5m in north direction and turns left to move 12m. What is the a) Distance, b) Displacement associated with the movement?
9. A man keeps 12 steps in north direction and turns right to keep 5 steps. He then returns to the initial point by the shortest path. Find a) Distance travelled. b) Displacement. Given step is 0.4m.
10.A circular cycle track has a circumference of 308m (ABCDA) with AC as one of its diameter. A cyclist travels from A to D along the circular path. Find the distance moved by the cyclist and the displacement if AB is along west-east direction. B

11. If 5m/s and 10m/s are the velocities of a body having a uniform acceleration in some time interval, what will be its average velocity?
12. A train travels from
