2 Dimensional Motion, Forces
• Combining displacements or forces in 2 dimensions is not as straightforward as we have previously done– Not just simple addition or subtraction
• The direction for motion in 2 dimensions cannot be described by a simple plus or minus

The description for force and motion values get more
complicated (longer)

Description
Boy is walking 25 meters in the North East Direction
Displacement value is =
25m [NE] or 25m (45°)
![Page 10: Wednesday-Thursday Physics 11-14-15 Questions on Projectile project Test and Review Sheet More general 2 dimensional motion.](https://reader035.fdocuments.us/reader035/viewer/2022072014/56649e7b5503460f94b7d09e/html5/thumbnails/10.jpg)
2D values
• Always written in the formMagnitude, direction
• Several ways to write the direction
[ ] use some combination of North, South, East West and the angle of direction
A single angle measured from the horizontal axis pointing right (Polar coordinates)

Direction using N,S,W,and E
• Use brackets
• First letter is the cardinal direction line used as the start of the measurement of the angle
• Number the value of the angle measured
• Last letter is the cardinal direction towards which you measure (never on the same dimension)

Polar Coordinates
• Angle is from 0 to 360 degrees
• 0 and 360° point due east (to the right)
• Measured going counterclockwise
