State the principle of work-kinetic energy theorem.

The principle of work and kinetic energy (also known as the work-energy theorem) states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.

×1+x2/2,y1+y2/2

summation of p= summationof m×v cm

torque is the product of f and perpendicular distance of f from the line of action itsunitsr newton metre
