Question

i ) What does the slope of a displacement time graph represents?
ii) Can displacement- time sketch be parallel to the displacement axis? Give reason to
your answer.

Answer 1

Slope of a displacement time graph represent velocity

Because displacement is change in position with respect to time and change in displacement with respect to time is velocity.

Since displacement do not change with time I.e. particle do not change its position means particle is stationary. 

Answer 2

(I) slope = height / base
= d/t
=speed
(ii) no it cannot be possible because it cannot be possible that slope(s/t = velocity) keeps increasing but the time does not increase

hope this helps you
if it does then please mark as brainliest
have a great day :-)
