How do the Newton’s laws of motion contribute to the construction of bridges? Students have had to see Newton’s laws at least once in their lives, and even with that they probably do not know their application to such things as bridges. The first Newton’s law states that “an object moves in a straight line and at constant speed except to the extent that it interacts with other objects.” The main purpose of Newton's laws is to describe how objects move, since the typical bridges do not move with respect to the earth, according to Newton's law, the net forces on the bridge must be zero. In other words, when gravity pulls a bridge down, a force that pushes upward has to exist in order to counteract it. This force comes from the ground pushing
