Question

Derive the equations v = u + at, s = ut + 1/2at² and v² = u² + 2as graphically.

Answer 1

(i) First Equation:

Suppose a body has initial velocity ‘u’ (i.e., velocity at time t = 0 sec.) at point ‘A’ and this velocity changes to ‘v’ at point ‘B’ in ‘t’ secs. i.e., final velocity will be ‘v’.

(ii) Second Equation:

(iii) Third Equation:
