Question

Why don't we expect the position-time graph of a uniformly accelerated motion to be a straight line ? ​

Answer 1

We don't expect the position-time graph of a uniformly accelerated motion to be straight cause the x-t graph for uniform motion is a straight line. Uniform motion simply means zero acceleration.

Uniformly accelerated motion taken as a whole is a result of non uniform motion of the body. And the x-t graph of non uniform motion is curved.

Refer to the attachment for info:-

1. Graph 1 is x-t graph for positive uniform acceleration

2. Graph 2 is x-t graph for negative uniform acceleration.
