Question

Name the physical quantity that is obtained by the slope of a :

3Page 5 of 13(i) distance-time and velocity-time graph of a body ? (ii) Can distance-time graph be parallel to the distance axis ? Give reason for your answer. Interpret distance-time graph which is parallel to time axis. List any two affects that a force can produce in a body

Answer 1

(i)

slope of distance-time = speed

slope of velocity-time = acceleration

..

(ii)

Yes distance-time graph can be parallel to the x-axis (time axis) and in this case the body will be at rest.

..

(iii)

Force can cause

- change in shape

- change in velocity

of a body
