Q.8.what does the slope of a distance-time graph gives ?


Q.9. what does the area of a velocity-time graph gives ?


Q.10. give two examples of vector guantity?

Answer 1

Hi!!!!!

1. displacement is the shortest distance between two points. it is vector

2. distance is the length of space between two points

3. the statement is true as displacement can only be =<distance

4.yes it is possible as when we throw an object upwards, when it reaches the peak, it has negative acceleration but 0 velocity

5.it is constant

6.the acceleration is negative (retardation)

7.no acceleration as velocity is constant there is 0 acceleration

8.the slope of distance time graph gives speed

9.

10. two example of vector quantity are:
displacement and
momentum
