Egipment 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 (U ), acceleration (a ), etc. 2. Representations of a vector: (a) Symbol: for example, 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. (c) Components: F = F.+ F, = Fox+ F,y, where x and y are unit vectors (or direction vector), which are used to indicate the directions of the x and y axes respectively. A unit vector is a vector of length 1, i.e., * = =1 The two components of F : F. = Fcos0, F = F sine The magnitude of F : F = F2+F?, F = Fy x The direction of F : tan 0 = F, / F., or 0 =tan-' (F, / F.) F = FX Figure 1 Components of F Note: a vector can be moved from one location to another in space as long as its magnitude (length) and direction are kept unchanged. This property will be used in vector sum. 3. Graphical representation of vector sum (vector addition and subtraction) (a) Parallelogram Method Figure 2a shows the addition of two vectors, i.e., A + B using parallelogram method in which A and B are the adjacent sides of the parallelogram. The arrow diagonal of the parallelogram R is the resultant vector or vector sum of A + B, i.e., R = A + B. (b) Triangle Method and Polygon Method An equivalent method of finding R is to add the two vectors "head to tail": the head of A to the tail of B, as shown in Fig. 2b. The resultant vector R is drawn from the tail of the vector A to the head of B. If more than two vectors are added, the head to tail method forms a polygon inwhich the resultant vector ft is drawn from the tail of the rst vector ( H )to the head of the last vector (5 }, as shown in Fig. 2c. - _ ft ' f: R : B E .3 A =+fs =1+ =i+i+ff {a} Farallelograrn method {b} Triangle method (c) Polygon method Figure 2 Graphical representation of vector sum 4. Analytical representation of vector sum .... Component Method By the reverse process, we may resolve a vector into x and y components (Fig. 3a). The resultant vector or the vector sum of any number of vectors can be obtained by adding the x and y components of these vectors (Fig. 3b}. _. R = a; +152; = always Rx =Rcos9, R1, = Reine?

The rim of the circular table is calibrated in degrees. Weights (gravitational forces) are applied to a central ring by means of strings running over pulleys and attached to weight hangers. The magnitude of a force is varied by adding or removing slotted weights and the direction is varied by moving the pulley. Figure 4 Force Table The resultant force of two or more forces is found by balancing the forces with another fbrce so that the ring is centered on the central pin. The balancing force is not the resultant R , but rather the equilibrant E , i.e., the force that balances the other forces and holds the ring in equilibrium. The equilibrant is the vector force of equal magnitude, but in the opposite direction to the resultant, i.e. R=E. 131+ F2 = il=-E' E (equilibran E (resultant) Figure 5 Rasultant and equilibrium forces Gravitational force 13 = m g is the gravitational force acted on (or the weight of) an object, where m is the mass of the object, g is the gravitational acceleration with a magnitude of 9.8!} n'iis2 on earth surface. Attention: In this experiment we take the value of g 2 10.0 at! :32 rather than 9.8!] m I s2 for the gravitational acceleration so that when use the graphic method to do vector sum we can use a scale of 2 cm for 1 N on the graphic sheet, i.e., seating factor is 0.5 Mom. The magnitude of the gravitational force F = [F' = m g. In SI units, or is in units of kg (kilograms), F is in units ofNINewton], 1N =1tgximret. Notations used in the following three measurements: (a) In the following three measurements, each force is produced by a hanging mass on which the value of the mass is labeled in units of g (gram) rather than kg. (b) The meaning of the notations used in following titres measurements, for example, Fl :2l} g at 0.00 means that 131 is produced by a hanging mass of 21m g at dill)\
