Question

Give one example where the displacement is zero but the distance traveled is not Zero
2. The terms motion' and 'rest' are relative. Justify the statement with the help of an example.

3. What will be the ratio of magnitude of displacement to distance in a given situation?​

Answer 1

Answer:

1).yes,displacement can be zero even when distance is not zero

example :- when a body travels in circular path , after covering a circle the distance cannot be zero,but its displacement is zero..

2).by finding the slope of distance time graph,we can find the speed of the body.

3).by finding the integrating of speed time graph ,we can find the distance.

4).yes,a body can have zero velocity and still acceleration.

example- in vertically upward projected body,at its highest point,the velocity becomes zero but still acceleration due to gravity acts on it

5).no its not possible ..when the speed is zero..its velocity will be zero

Explanation:

Answer 2

Answer:

1/ when u travel from ur home to a certain place and then again return to ur home ..in this case displacement is 0 but distance is the total path length

2/ like if anyone is sitting in the train and an observer on the platform is observing him and the train is moving so in this case the person who is sitting in the train will be in the rest wrt to him but he will be in motion wrt to the other observer..

3/it will always be 1 as magnitude of the displacement is equal to the distance....

hope it helps....!!!!
