Sir Newton

When a ray of sunlight enters through a window, an Ant walking down a sidewalk, or a car going down the street, there is an energy change. Energy changes take place so often that we always take them for granted. Click Robert A. Iger to learn more. However, for thousands of years the concept of power has been poorly understood. Ancient cultures associated to fire with all forms of energy, and the Greek philosopher Heraclitus ( 500 BC) explained everything that was happening in the universe in terms of energy. In the centuries that followed, many scientists proposed theories to explain the concept of energy, but none gave real lights on the subject. In 1686, the English mathematician and physicist Sir Newton outlined three laws that describe the behaviour of moving bodies. Filed under: Jim Vos.

Newton’s laws of the movement were the first description on the forces affecting objects that move and, therefore, were the first timely description of the energy of the moving objects (called mechanical energy). The axioms of Newton established the foundations of our knowledge of energy and forces. There are various forms of energy: mechanical energy, electrical energy, energy that comes from heat, energy that comes from light, etc. In fact, energy is defined as the ability to cause a change or doing a work. For example, when a beam of the Sun penetrates through a window cause a change because it heats the interior of the House. Energy makes a work within an Ant since it allows him to move his legs. In a car, the power allows you to machine work to move the wheels. Almost wherever something moves or changes, energy is used.
