________ pulls with 120 Newtons of force at 45° as show.
Sam
________ pulls with 200 Newtons of force at 60°.
Vectors
________ help explain that.
common way
The most ________ is to first break up vectors into x and y parts, like this: The vector a is broken up into.
C
________= (8, 13) + (26, 7)= (8+26, 13+7)= (34, 20)
Y
________= r × sin (θ)= 200 × sin (60°)= 200 × 0.8660= 173.2.
scalar
A(n) ________ has magnitude (size) only.
magnitude of a vector
What is shown by two vertical bars on either side of the vector: OR it can be written with double vertical bars (so as not to confuse it with absolute value): We use Pythagoras 'theorem to calculate it:
vector a
The most common way is to first break up vectors into x and y parts, like this: What is broken up into? Answer with a single words or term.
length of the line
The ________ shows its magnitude and the arrowhead points in the direction.
Y
________= r × sin (θ)= 120 × sin (−45°)= 120 ×- 0.7071= −84.8.
