Question

If the figure given below represents a parabola, identify the
physical quantities representing Y and X for constant acceleration:
(A) X = time, Y = velocity
(B) X = velocity, Y = time
(C) X = time, Y = acceleration​

Answer 1

$\:\: \underline{\underline{\bf{\large\mathfrak{~~Solution~~}}}}$

option (a)=X = time, Y = velocity

reason

as velocity is increasing with time in regular manner so ..at an instant of time it will increase abruptly for just small increasing in time ......

so that is why the impression of the curve is like parabola.......

Answer 2

Answer:

Since, body has uniform acceleration. So, velocity of particle is increasing with time. Hence, this is  displacement-time graph with X as time axis and Y as  displacement axis.

X = time, Y= displacement

Explanation:

One option is missing here!!

It is option (d) X= time , Y = displacement.

Hope it's helpful to you!!!
