Accelerated motion is represented by a line on a nonlinear distance-time graph.

Accelerated motion could be changing speed, or changing direction, or both.

If it's only the direction changing and not the speed, then you'll never see it on a distance/time graph.

If the speed is changing, then a velocity/time graph can be any kind of a line except horizontal or vertical, and a distance/time graph must be curved.

Accelerated motion is represented by a CURVED line on a nonlinear distance-time graph.

Explanation:

For uniform acceleration we know that

now integrating both sides we will have

now after integration we will have

now we have

again we know that

again by integration both sides

now since this equation is a quadratic equation so here distance time graph must be a curved graph

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
