BRiCS: BUILD ROBOT CREATE SCIENCE's video: Third Equation Of Motion Derivation Using Integral Method

This video is all about derivation of Thrid Equation Of Motion Using Definite Integral Method. Newton's 3rd equation of motion consists of final velocity (v), initial velocity(u), displacement (s) and constant acceleration (a). The equation is as follows- v²= u²+2as Solving for a body under constant acceleration, for a displacement 0 to s, (initial velocity=u, final velocity=v) a = dV/dT multiply divide by dS a= dV/dS * dS/dT dS/dT is equal to velocity ( rate of change of displacement) a= dV/dS * V a*dS = V*dV Integrate both sides (P.S: integreal signs as well as limits aren't possible in the keyboard) (Integral x = x^2/2) (a constant) (Integral dS = s) [V^2/2] (limit u to v) = a [S] (limit 0 to s) V^2/2 — U^2/2 = a ( s-0) V^2 — U^2 = 2as V^2 = U^2 + 2a
