Vectors Flashcards
Vectors
Represent any quantity having a magnitude and direction
Resultant
A single vector representing the SUM of 2 or more vectors ( The result of adding vectors)
Angle between vectors acting in the same direction?
0 degrees
vectors acting in the same direction produce
largest resultant
How to find the resultant force of vectors acting in the same direction?
Add the magnitudes together (direction stays the same)
Angle between vectors acting in opposite directions?
180
How to find the resultant force of vectors acting in opposite directions?
subtract the magnitudes
vectors acting in opposite directions produce
smallest possible resultant
What direction do vectors acting in opposite directions go in?
Direction is that of larger vector
Vectors at right angles?
-Complete the “parallelogram”
Head to tail method
- 3 way forces
- Draw them one at a time, each new one starting where the last one ended
To find resultant force
goes from where you started to where you ended
