Resolving Vectors

This links to [[Physics - Combining Vectors]]^A, since it’s like doing it in reverse.

What is resolving vectors?

Finding the horizontal and vertical component of a vector.

What is resolving vectors opposite to…?

Combining a vector.

How is the the horizontal component of $F$ written?

$F_{x}$ .

What is $F_{x}$ ?

The horizontal component of vector $F$ .

How is the the vertical component of $F$ written?

$F_{y}$ .

What is $F_{y}$ ?

The vertical component of vector $F$ .

What are the components of a vector?

The horizontal and vertical vectors that are at right angles and combine to give the original vector.

What do the horizontal and vertical components of a vector look like?

What is the formula for the vertical component of a vector $F$ ?

F_{y} = F \sin θ

What is the formula for $F_{y}$ of vector $F$ ?

F_{y} = F \sin θ

What is the formula for the horizontal component of a vector $F$ ?

F_{x} = F \cos θ

What is the formula for $F_{x}$ of vector $F$ ?
