LESSON 1: UNITS, VECTORS
Measurement Units
Meter (m): Measures length.
Kilogram (kg): Measures mass.
Second (s): Measures time.
Prefixes
Milli- (m): 10⁻³
Centi- (c): 10⁻²
Kilo- (k): 10³
What are vectors
Quantities that have both magnitude and direction
Ways To Represent Vectors
Graphically
Component Form
Add 2 or more vectors
Use Pythagoras Theorem
What are Scalars
Quantities that only have magnitude and no direction
Trigonometry and Pythagoras Theorem
a^2 + b^2 = c^2
Trigonometric Ratio
Sine = Opp/Hyp
Cosine = Adj/Hyp
Tangent = Opp/Adj
Sine Law and Cosine Law
a/SinA = b/SinB = c/SinC
c^2 = a^2 + b^2 - 2ab cos C
