Sir Isaac Newton was an English Mathematician, astronomer, theologian, author, and physicist who was able to come up with the laws of motion in the “Principia Mathematica Philosophiae Naturalis.” He was born on January 4, 1643 in Woolsthorpe, England and died on March 31, 1727, in London. Just as age 23, Newton spread the theories of gravitation in 1666. With his first, second, and third law, people were able to understand motion and force more. These discoveries answered two main questions in science. From an apple falling off a tree, this made science history. People seemed to ask these questions plenty of times; “Why do objects fall toward Earth, and what keeps the planets moving in the sky?” Since Sir Isaac Newton knew about how unbalanced forces worked, he took an apple falling off a tree as an example. This concluded that an unbalanced force makes apples fall from trees. He then backed it up saying that an unbalanced force on the moon keeps it moving circularly around Earth. The two forces ended up being the same which was called gravity. Newton then made gravity in a law; which is now known as the law of universal gravitation. …show more content…
“An object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.” He used a clause diagram to figure out how the 1st law works. When an object is at “rest” it means it’s not moving unless they are acted on by an unbalanced force. For instance, a push or pull has to be present on the object so it can move. (v=0m/s^2) Any artifact in motion means the item will be moving with a certain velocity so it can continue to move faster until an unbalanced force acts on it.
