Question

What does the tangent at a point to the position-time graph for an object in non-uniform motion along a straight line represent?

Answer 1

The tangent is always given by the slope of the graph. Simply divide the quantity on y axis by the one on x axis . So the tangent of a position time graph will represent velocity at that particular instant.

Answer 2

Answer:

It represents the instantaneous velocity with which the object is movung at that time.
