| The Relativity of Space and Time |
| Newton's idea of the Universe: |
 |
| Every object moves uniformly in a straight line unless acted on by an external force |
| The Fundamental Laws |
 |
|
| When a force does act, the object's Velocity changes at a rate proprtional to the force and inversley proportional to it's mass |
| For a clearer explanation of Newton's theories click here |
| These laws are used to explain planetary orbits and how apples fall from trees |
| Problems for Newtonian mechanics soon arised |
| NM is built entirely on the concept that space and time are absolute |
| Absolute space: |
| Space consists of three dimensions: east-west, north-south, up- down (x, y, and z). There is only one space. This space gives us our sense of length and breadth and height. |
| Absolute time |
| It is the time that ages us, the time measured by clocks,the rotation of the Earth and the motion of the planets cover |
| If these foundations were to be proved wrong,Newtonian Mechanics would need to be revisited and revised |
| Michelson-Morley experiment sort to find the answe |
| (For information on this experiment, consider some of the following sites): |
| Between any two objects in the Universe there acts a gravitational force that is proportional to the product of their masses and inversely proportional to the square of their separation. |
|
| What does absolute space and time mean? |
