Ideas in the subject of Physics are never absolute; it is a forever-changing topic. We think we have discovered everything there is to know about it, and then we find out something new that changes everything. That is one of the reasons physics is so interesting to learn about – there will always be something new. There are many very important discoveries in Physics. This paper will describe some of the discoveries. These discoveries are prevalent throughout history and in our daily lives. One of the oldest, but nonetheless important, discoveries in physics is The Law of Falling Bodies. Discovered by Galileo Galilei, it remains a fundamental part of physics even today. It states that all objects that are falling, no matter mass, height,…show more content…
If they were not important then people would not have heard so much about them. Isaac Newton was a mathematician and physicist that discovered the three laws of motion. The laws are as follows: “1) An object in motion remains in motion unless an external force is applied to it. 2) The relationship between an object's mass (m), its acceleration (a) and the applied force (F) is F = ma. 3) For every action there is an equal and opposite reaction.” With these three laws, Newton created the basis for modern day engineering. These laws helped many other physicists to discover meaningful things. Newton’s first law of motion is usually referred to as the law of inertia. Inertia is defined as “the property of matter by which it retains its state of rest or its velocity along a straight line so long as it is not
