Net Force
In mechanics, net force refers to the sum of all the forces acting on an object. When multiple forces act upon an object in different directions, the net force is the single force that represents the combined effect of all these forces. This net force determines the objects acceleration, as described by Newtons second law of motion. The net force is a vector quantity, taking into account both the magnitude and direction of the forces acting on the object. It is calculated by summing the individual force vectors that are acting upon the object.
When the net force is not zero, the objects motion will change in the direction of the net force. If the net force is zero, the object will either remain at rest or continue to move at a constant speed, a state known as equilibrium.
In summary, the net force is a fundamental concept in physics that helps to understand how forces interact and influence the motion of objects.
