Equation of Motion
Equations of uniformly accelerated motion 1) First equation of motion v = u+at 2) Second equation of motion S = ut + 1/2 at2 3) Third equation of motion v² = u² + 2aS If a body starts from rest then u=0 If a body comes to rest then v=0 If a body moves with uniform velocity then a=0 u = Initial velocity of the body v = … [Read more...] about Equation of Motion
