Isaac Newton
He was one of the greatest mathematician and scientist that ever existed. This thinker invented the three laws of motion. The first one often called “The Law of Inertia”, states that an object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the direction unless acted upon by an unbalanced force. In an easier way to understand it, “An object keeps on doing what they’re going.” This law helps us understand why we keep going forward when a car accident occurs, or how a rocket can be lifted from the floor. “The second law of motion” states that acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). The formula for this law is FORCE equals MASS times ACCELERATION (F=MA). “The third law of motion” states that for every action there is an equal but opposite reaction, which means that for every force there is a reaction force that is equal in size, but opposite in direction. These three laws of motion helped us understand why things happen the way they happen in the universe.
There is a popular story that Newton was sitting under an apple tree, an apple fell on his head, and he suddenly thought of the Universal Law of Gravitation. “Newton's Law of Universal Gravitation” states that any two bodies in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This particular law helps us understand why everything falls back to the floor. Only at a certain high the object will then start orbiting around the earth and never stop unless another objects intersects it.
