Motion |
The main contribution that Isaac Newton had in motion was creating Newton's 3 laws of motions:
These 3 laws have been fundamental in understanding how the world works and has created a foundation for many other scientists to expand on his knowledge and create new laws and understandings. These laws can all be found in the original copy of Isaac Newtons publication Principia. |
Gravity |
In Isaac Newton's publication Principia there is Newton's Theory of Gravity, which states that every mass attracts every other mass that the gravitational force exerted by one body on another is proportional to its mass, and inversely proportional to the square of the distance between them.
This theory explains how people and animals aren't floating up into space, why when someone jumps they come back down and why and apple falls off a tree. |
Optics |
During the time that Isaac was at College and a Professor he was studying Optics, one of his major discoveries was that 'white' light is actually made up of a spectrum of colours. To find this out he used a glass prism to break apart the light into a rainbow of colours.
Another major invention of Newtons was the Newtonian telescope. In that time period they had been using the refracting telescope, but this telescope couldn't display clear or accurate images. Isaac replaced the mirrors in the refracting telescope with a combination of lenses and multiple mirrors placed at angles to each other, this made the telescope significantly smaller and display clear images with powerful magnification. |
Mathematics |
Isaac Newton's main contribution in Mathematics was creating Calculus, or as it was called 'method of series and fluxions'. Calculus is basically the opposite of geometry, it provides methods for working out problems with curves - such as plant orbits. Calculus can also solve problems that have things that are continually changing - such as the speed of falling objects.
