Class Response: Newton's Laws of Motion

In class, we have just learned some ideas of who Issac Newton was. He was a scientist, inventor, mathematician, astronomer, physicist, natural philosopher, and obviously one of the most inspiring men. However, we learned something more important. This happens every single day of our daily lives. Issac Newton developed the Laws of Motion. In fact, there are three laws of motion, each describing and showing how gravity, forces, acceleration, rest positions, friction, and countless other topics act. Newton's First Law of Motion, states that an object would remain at rest, unless an external force acts upon it. For instance, a book would stay or remain at it's place, until someone, or something applies a force to it. Therefore, that force would make slide, move, or just be flung out of the way. Newton's Second Law of motion shows how mass, acceleration, and force are related. For example, F=ma, which means that FORCE = MASS * ACCELERATION. This also shows how a smaller car has a better mileage than a larger one. This is all because of its mass, shape, and acceleration. Lastly, Newton's Third Law of Motion states that for every single action, there is an equal and opposite reaction. For instance, when we walk, the opposite reaction is the ground or floor we are moving around. This also relate to friction.
In conclusion, in my own opinioin, Issac Newton was an incredible man who solved how science revovled around us, and how everything happens the way they would result.
