Negative of vector has
- Same loa
- Same mag
- Opp sense
- Same point of app
---------------------------------------------------------Vector algebra
Vector addition is
Commutative p + q = q+ p
Associative p + q + s = (p + q) + s = p + (q + s)
--------------------------------------------------------------------Product of a vector with a scalar scales magnitude
If the scalar is negative his also flips the sense of the vector
-----------------------------------------------------------------------------Particles are objects with dimensions small enough to be ignored ( . )
Particles can be acted upon by forces in the form of vectors
--------------------------Parallelogram
1. Draw a nice figure
2. Draw dotted lines along the line of action off each vector (optional_)
3. Draw dotted lines out of each arrowhead parallel to the other LOA
4. Draw a line from particle to intersection of previous lines
