How to eliminate vectors to get the magnitude of the Force?
 Take the squared product of the x component and the y squared product, sum them, then take the square root of the number.
 For example:
 to find the magnitude of C given
 →
 C = (A)x + (B)y
 then
 C= √(A^{2}) +(B^{2})


Dot Product
The magnitude of one vector time the magnitude of the other vector times the cosine of the angle between the two vectors.

Work is positive
 when Force and component are going in the same direction'
 speed increases

Work is negative
 when the force and the component in the direction of motion is opposite
 speed decreases

Work is zero
When Force and the component of motion are at a 90 degree angle
