THE PRACTICE STUDIO
Go slowly. Ask why. Make it yours.
PRACTICE / Unit vectors
Keep the sign while removing the magnitude
A displacement is −6 m along x and +8 m along y.
What is the x component of the unit vector in its direction?
Organize the givens & assumptions
- rx = −6 m
- ry = +8 m
Orthogonal Cartesian axes in a plane. A unit vector is dimensionless and points along the nonzero displacement.
- A
- B
- C
- D
