Gravitational Force is the force of attraction between all matter.
It is everywhere in our universe and affects everything in it. However, it is orders of magnitude weaker than the other forces. All of the other fundamental forces – Electromagnetism, the Strong Force, and the Weak Force, have strengths roughly within a similar range to each other. Gravity is on the order of 1040 times weaker than other fundamental forces in the universe. That means that gravity is 1/10,000,000,000,000,000,000,000,000,000,000,000,000,000 – or, a one hundred quintillionth the strength of the other forces.
General Relativity says that although gravity is not in reality a force, the geometry of space time creates the appearance of a force.

Real Vector Space
A Real Vector Space is a Vector Space whose vectors are described by real numbers. We can describe our classical three-dimensional space as simply a Vector Space with three degrees of freedom – or dimensions. Such a space would be labeled: This…

Scalar Function
A scalar function is a function of one or more variables whose range is one-dimensional, as compared to a vector function, whose range is three-dimensional (or, in general, n-dimensional).

Vector Space
A Vector Space is a set of vectors that may be added together and scaled. When we say they may be scaled, we mean that they may be multiplied by numbers called scalars. For example, we may multiply all of the vectors…
