Engineering Mechanics
If u₁ and u₂ are the velocities of two moving bodies in the same direction before impact and v₁ and v₂ are their velocities after impact, then coefficient of restitution is given by
Is equal to twice the area of the triangle, whose base is the line representing the force and whose vertex is the point, about which the moment is taken
Is the turning effect produced by a force, on the body, on which it acts
All of these
Is equal to the product of force acting on the body and the perpendicular distance of a point and the line of action of the force
