Mechanics
Units of measurements
Seconds (time)
Grams (mass)
Meters (length)
Prefixes of units
g (mass)
m (length)
s (time)
Vectors
unit of measurement which has magnitude, unit, and direction
Different from scalars cause of direction.
vector + vector = vector
Use a direction and a unit, ie. 7N left
Pythagoras theorem & formulas
a^2+b^2=c^2
Sine law
sin(A) / a = sin(B) / b = sin(C) / c
Cosine law
a² = b² + c² - 2bc * cos(A)
b² = a² + c² - 2ac * cos(B)
c² = a² + b² - 2ab * cos(C)
