Question

In a position to answer the following questio
1. Is displacement a scalar quantity ?
2. A body is moving along a circular path of radius R. What will be the distance travelled
and displacement of the body when it completes half a revolution ?
3. Fill up the blanks with suitable words in the following:
Displacement is a .......... quantity whereas distance is a .......... quantity.
4. What is the difference between distance travelled" by a body and its "displacement" ? Explain
with the help of a diagram.
5. State whether distance is a scalar or a vector quantity,
6. If on a round trip you travel 6 km and then arrive back home :
(a) What distance have you travelled ?
(b) What is your final displacement ?
7. Define motion,
8. Under what conditions can a body travel a certain distance and yet its resultant displacement
be zero ?
9. A body travels a distance of 3 km towards East, then 4 km towards North and finally 9 km
towards East :
(1) What is the total distance travelled ?
(ii) What is the resultant displacement ?
