Answer:
Equation of motion by graphical method.
Derivation of v=u +at. Initial velocity u at A =OA. ...
Derivation of S = ut +1/2 x at 2 The distance travelled by the body is given by area of the space between velocity time graph AB and time axis OC , which is equal to area of figure OABC. ...
Derivation of v2 = u2 + 2as
Hence, these equations are used to derive the components like displacement(s), velocity (initial and final), time(t) and acceleration(a). Therefore they can only be applied when acceleration is constant and motion is a straight line.
...
The three equations are,
v = u + at.
v² = u² + 2as.
s = ut + ½at²
