PHY2048L 007 Experiment 4: Force Table
February 14, 2022
Purpose
The purpose of this experiment is to add a set of vectors using three different methods (graphical,
analytical, and experimental) to find the resultant vector.
Equipment
Force table with pulleys, weight hangers, a set of slotted weights (masses), string, protractor,
compass, rulers (15 cm and 30 cm), bubble level, graph papers.
Theory
1. Scalar quantity and vector quantity
(a) Scalar: a quantity can be specified by magnitude alone such as time (t), mass (m), volume
(V), etc.
(b) Vector: a quantity must be specified by both magnitude and direction such as force (⃗
F) ,
velocity (υ⃗ ) , acceleration (⃗a ) , etc.
2. Representation of a vector
(a) Symbol: ⃗
F , the top arrow indicates that force is a vector, F ¿∣⃗
F∣ is its magnitude.
(b) Graphic: ⃗
F The direction of the arrow gives the direction of the force.
The length of the line is proportional to the magnitude of the force.
