Forces acting in the same direction on an item add to one another. When two forces operate on an item in opposing directions, the net force exerted on it is equal to the difference between the two forces. A force might be stronger or weaker than the other, or they could be equal. The magnitude of a force is commonly used to describe its strength. We must additionally indicate the force's direction of action. Also, if the applied force's direction or magnitude varies, the impact changes as well.
