Euler's law :
The rate of change of angular momentum of a body about an origin O equals the moment impressed upon it about the origin.
The state of rest or of motion of a rigid body is unaltered if a force acting on the body is replaced by another force of the same magnitude and direction but acting anywhere on the body along the line of action of the applied forces. In the following animation, two rigid blocks A and B are joined by a rigid rod. If the system is moving on a frictionless surface, the acceleration of the system in both the cases is given by,
Acceleration=Applied force/total mass
It is independent of the point of application
