Newton’s laws 01/28/16
For any student of Physics, Newton’s three laws are some of the most paramount and sumptuous facets of the course of study. These laws are the axioms on which the framework of Newtonian mechanics are contingent upon.
We shall embark our journey with the explanation of Newton’s first law, the law of inertia. Newton’s first law dictates that an object at rest stays at rest and an object in motion stays in motion unless there is a net external force. To illustrate, if one were to throw an object suffused in the vacuum of space, then the object will continue in its trajectory unless it is impinged by an external force, such as gravity or if it encounters air resistance. Likewise, an object at rest will remain at rest unless a force is acted upon it.
Newton’s second law states is the law of forces, which states that a force is equal to an object’s change in momentum, pretty much Force is the derivative of momentum, or F=ma (Force is equal to mass * acceleration). This gives us a mathematical description of force, which allows us to further develop any concepts.
Newton’s third and final law states that For every force, there is an equal and opposite force acting upon contact. To give a concrete example, remember anytime you struck your pillow, you felt a force knock back at you? That was Newton’s third law in action, you exerted a force on the pillow and the pillow exerted a force on you.
