In fact, newton’s Third law states that the force is accurately equal in magnitude and opposite in direction of the force we exert on the box. If I am in a boat, I cannot interchange the boat simply by pushing on the back. Nevertheless, I do apply a force on the boat; I also feel a force in the opposite direction. Thus the net force on the arrangement (me and the boat) is zero, and the boat doesn’t move. We requisite some external force, like wind, to move the boat. And yet this law seems obvious and unnecessary, we will see its importance when we apply Newton’s laws. Instead of just a push or a pull, we can now recognize a force as the shared interaction between two bodies. Each time two bodies interact in the physical world, a force results. Whether it be two spheres bouncing off each other or the electrical attraction among a proton and an electron, the collaboration of two bodies consequences in two equal and opposite forces, one performing on each body complicated in the

English physicist and mathematician Sir Isaac Newton, most renowned for his law of gravity, was contributory in the scientific revolution of the 17th century. With discoveries in optics, motion and mathematics, Newton technologically advanced the principles of modern physics. In 1687, he distributed his most commended work, Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy), which has been named the single most influential book on physics. His work compromises an exact quantitative explanation of bodies in motion in three basic laws: 1) A unmoving body will stay stationary unless an external force is applied to it; 2) Force is equal to mass times acceleration, and a change in motion is proportional to the force applied; and 3) For every action, there is an equal and opposite reaction. These three laws aided to explain not individual elliptical planetary orbits but nearly every other motion in the universe; how the planets are retained in orbit by the attraction of the sun’s gravity; how the moon rotates around Earth and the moons of Jupiter revolve around it and how comets revolve in elliptical orbits universally around the
