Detailed explanation-1: -When a force is applied to the body, not only is the applied force acting, there are many other forces like gravitational force Fg, frictional force Ff and the normal force that balances the other force. Therefore, the net force formula is given by, FNet = Fa + Fg + Ff + FN.
Detailed explanation-2: -The net force is the vector sum of all the forces. That is, the net force is the resultant of all the forces; it is the result of adding all the forces together as vectors. For the situation of the three forces on the force board, the net force is the sum of force vectors A + B + C.
Detailed explanation-3: -Formula of Resultant Force F (1), F (2), F (3) are the three different forces that are acting upon a body in the same direction. F(R) = [(F (1) ^2+F (2) ^2)] ^ 1/2. Using the Pythagorean Theorem, the sum of the vectors is taken as the vectors as they have a particular direction.
Detailed explanation-4: -The net force is the vector sum of all the forces acting on an object. When an object is in equilibrium (either at rest or moving with constant velocity), the net force acting on it zero. A vector can only have zero magnitude if all of its components are zero.
