Definitions for net force
This page provides all possible meanings and translations of the word net force
the combination of all the forces that act on an object.
In physics, net force is the overall force acting on an object. In order to perform this calculation the body is isolated and interactions with the environment or constraints are introduced as forces and torques forming a free-body diagram. The net force does not have the same effect on the movement of the object as the original system forces, unless the point of application of the net force and an associated torque are determined so that they form the resultant force and torque. It is always possible to determine the torque associated with a point of application of a net force so that it maintains the movement of the object under the original system of forces. With its associated torque, the net force becomes the resultant force and has the same effect on the rotational motion of the object as all actual forces taken together. It is possible for a system of forces to define a torque-free resultant force. In this case, the net force when applied at the proper line of action has the same effect on the body as all of the forces at their points of application. It is not always possible to find a torque-free resultant force.
