Experiment #4:
Force Table
The purpose of this experiment is to add a set of vectors using three methods:
graphical, analytical and experimental to find the resultant vector.
The theory behind this experiment is to measure the scalar and vector quantity. A
scalar quantity can be specified by its magnitude alone such as time (t), mass (m),
volume (V), etc. A vector quantity must be specified by both its magnitude and
direction such as force (F), velocity, acceleration due to gravity (g), etc. There are
three representations of a vector: symbol, graphic and components. The graphical
representations of vector sum are the parallelogram method and the triangle &
polygon method. The analytical representation of vector sum is the component
method. We also used the Force Table that allows the experimental determination of
the resultant force.
