EXPLAIN the difference in motion when there is a straight, linear line or a curving line on a “displacement vs. time” graph.

Solution

the slope of a displacement time grpah is velocity

in straight line graph slope is positive and constant

so velocity is constant and acceleration is zero

that is body moves with a uniform speed

in curving line slope is increasign that is body is acceelratig
