... • Newton’s 2nd Law is the relation between acceleration & force. • Acceleration is proportional to force and inversely proportional to mass. It takes a force to change either the direction of motion or the speed of an object. • More force means more acceleration; the same force exerted on a more mas ...

... Mathematical verification of m1u1+m2u2= m1v1+m2v2 : Let us consider 2 balls having masses m1 and m2 respectively. Let the initial velocity of ball A be u1 and that of ball B be u2 (u1>u2). Their collision takes place for a very short interval of time t and after that A and B start moving with veloci ...

... rB rA O To derive the moment of the couple, consider two vectors , rA and rB from O to points A and B lying on the line of action of F and - F. The moment of the couple about O is: M = rA x (F) + rB x (-F) = (rA - rB) x F By triangle law of vector addition, rB + r = rA or r = rA - rB So: M = r x F T ...
