Question

How to calculate the slope of position time graph ?

Answer 1

Answer:

Slope= $\frac{x2-x1}{t2-t1}$

Explanation:

We are supposed to find the slope in a position time graph,

For that we need atleast two points $(t1,x1),(t2,x2)$.($(x,y )$ represents there coordinates in respective axis directions.)

In the given case the y axis would be the position and the x axis as time .

Slope is defined as the ratio of change in y coordinate to change in x coordinate :- $\frac{y2-y1}{x2-x1}$

So subsituting the coordinates of position and time we get slope as:-

$\frac{x2-x1}{t2-t1}$

[When we have more than two points which are not collinear then to calculate the slope we take the average.]
