Jacob's+Einstein

Einstein's theory of relativity is basically viewed as a fabric. Where planets and objects in space are placed in this "fabric" appears a dent. When you are in the curve of the dent you are in the objects gravitational field. He also theorized that no matter where you observed the speed of light it would always be the same.

Classical mechanics is used for describing the motion of macroscopic objects, from projectiles to parts of machinery, as well as astronomical objects , such as spacecraft, planets , stars, and galaxies .Classical Mechanics viewed objects as point particles with "negligible" size. Classical Mechanics is also known as Newtonian Physics.
