Document Summary
A force is a push or a pull. A force is an interaction between two objects or between an object and its environment. A force is a vector quantity, with magnitude and direction. Any number of external forces applied to an object has the same effect as a single force equal to the vector sum of the external forces. Every body continues in its state of rest or of uniform motion in a straight line unless it is compelled by a force to change that state. That is, a body acted on by no net external force moves with constant velocity (which may be zero) and zero acceleration. When the net external force acting on an object is zero, the object is said to be in a state of translational equilibrium . F acting on an object of mass m is equal to the product of the object"s mass with its acceleration a.
