Introduction:
A vector is a physical quantity that requires a direction and a magnitude to be specified. Vector
quantities can be used to identify the
What are units for C that will make this equation unitically correct?
V= Cxat
m/s = C [m] [m/s] [s]
m/s = C [m2/s]
1/m = C
What are units for D & Z that will make this equation unitically correct?
X = D v2 t2 + Z a v t2
M = D [m2/s2] [s2]
M = D m2
1/m = D
CALCULATIONS
Percentage error= E-K divided by K and then x by 100
Absolute Error = (exp) (analytical)
Discussion:
We were able to figure out the resultant vector by vector addition with two applied forces. The
percent error magnitude experimental compared

are combined.
