Motion |
One of Newton's best known work were his 3 laws of motion.
All motion can be described by these three laws. Newton came up with these laws in 1686 (aged 43). |

GRAVITY
There was an incident in Newton's life (often known as the apple incident) that made him discover gravity. He was sitting under an apple tree when one fell on his head. This got him thinking and eventually, Newton proposed that there was a force in the Earth which he called gravity. He concluded that gravity is always attractive, it works instantaneously at a distance and has an infinite range. Gravity effects everything with mass and every single object, no matter what its mass is, will fall at the same rate. This is because an object's acceleration does not depend on its mass. |
MATHEMATICS |
In the two years that Trinity College was shut down because of the plague, Newton worked on the invention of calculus. He spent both years working on it and also acknowledged Gottfried Leibniz for his contribution. Calculus has given us a more accurate depiction of the behaviour of the universe. This is one of his well known contributions to mathematics but he also had a few others such as the study of power series, developing Newton's method for approximating the roots of a function and classifying most of the cubic plane curves.
