Question

Derive the equation v=u+at by graphical method

Answer 1

ANSWER:

Derivation of v=u +at

Initial velocity u at A =OA

Velocity changes from A To B in time t(uniform acceleration a)

Final Velocity v=BC

BC=BD+DC

v=BD+Ao

v=BD+u

Slope of velocity time graph is equal to acceleration a.

BD=at.

Therefore v=u+at.

Hence proved.
