Answer 1

Question :

Derive the first formula of motion with the help of a graph.

Solution :

Let us assume that the initial velocity is u and the final velocity is v.

The velocity is represented on the X axis .

Area of the graph gives displacement .

Slope of the graph gives time .

Velocity × Time = Constant

> VT = UT + area of triangle

> VT = UT + ½ × 2(V/T) × T³

> VT = UT + ½AT²

> V = U + AT ( Cancelling by 2)

Hence derived .
