Mention any two physical quantities which can be calculated from a velocity. .?

Answer»

The two easiest will be DISPLACEMENT from time t_1 to t_2, which is proportional to the area between the x-axis and the curve (underneath the axis is “negative area") from t_1 to t_2. (The integral)

And acceleration, which is the TANGENT at a point on the curve, vertical is high magnitude, horizontal is low magnitude. (The derivative)

Of course, you could apply either PROCESS continuously, but the physical graph can't really be used ANYMORE if it were, say, on a PIECE of paper or something.
