George Fountain III Lab IV Error Analysis Discussion 1. The difference between a vector and a scalar is that a vector contains both magnitude and direction. But a scalar has only a magnitude. Therefore, a scalar only involves number, but a vector can include numbers and a degree of direction. An example of a vector is the wind blowing 20mph northwest (magnitude and direction). An example of a scalar is how tall a person is (just a segment). 2. (see attached sheet) 3. Three unequal and non-parallel forces could all be in one quadrant, but they would not all be in equilibrium. This is because one may be stronger and they could eventually become perpendicular, depending on the exact direction the force is within that one quadrant. 4. Three unequal and non-parallel forces could be in two adjacent quadrants and be

In this case, they could be pulling toward each other in the same direction or pulling each other away at the same direction. 5. Based upon this experiment, the graphical method was more accurate. This is because there could have been many errors with the calculation of masses and when they got to equilibrium. Since the ring is not really tight against the center of the instrument, some room for difference is left in calculating how the equilibrium of the forces is perceived. With graphing, the calculating can be done with minimal error with a calculator using the SOHCAHTOA technique or Pythagorean Theorem....
