- Components of a Vector
A vector, F, generally has two components, namely the vertical component of a vector Fy, and the horizontal component of a vector, Fx.
F = (Fx, Fy)
The component of a vector is the effective value of the vector in a particular direction.
The horizontal component of a vector F is the effective value of the vector in the horizontal direction (Fx)
Use SOH CAH TOA to calculate the horizontal component Fx
Fx = Adjacent, F = Hypotenuse, Therefore, we use CAH
Cos θ = \( \frac{Adj}{Hyp} \)
Cos θ = \( \frac{F_x}{F} \)
Fx = F Cos θ
