Vectors and 2-D Kinematics - Vector Components Flashcards
1
Q
magnitude and direction
A
- magnitude: length
- direction: angle
2
Q
direction angle theta
A
- measure the direction angle theta from the +x axis , from 0 degrees to 360 degrees
3
Q
vector components
A
- B_x: x component; how far B goes on the x-axis
- B_y: y component; how far B goes on the y-axis
4
Q
+ and - vector components
A
- tell you on which side of the axis the vector is on
5
Q
finding vector components
A
- b_x = B cos(theta)
- b_y = B sin(theta)
- angle from +x axis
