Can force in newtons be negative
WebForces can be negative. Forces are vectors. Here is an example: you are pushing a box with a force of 5N. However, friction with the ground is pushing bat with a force of 2N. Hence, if you were to add all the forces … WebThe net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out. At this point, the rules for summing vectors (such as force vectors ...
