There are physical quantities that when being calculated have both a magnitude and direction. Those quantities are called vectors. Vectors are added or subtracted by lining them up head to tail and can be broken up into components to figure out their values. By using given values and certain formulas these vectors and vector components can be calculated. Along with these calculations there are uncertainties that have to be accounted for and can also be calculated by using certain given formulas. The value calculated here in this experiment was force using the equation f=mg. Experimental Procedure In this experiment we calculated vectors, angles, and forces using a force table. We used three pulleys with weights on the end of the ropes that acted as the vectors for the experiment. The object of the experiment was to balance out the forces by putting the vectors at certain angles so that the ring at the middle of the table would be centered. To find these angles you would adjust the pulleys along the table to line up the…show more content…
Next we added 50 grams of mass on one mass holder and set it to zero degrees on the force table. Then converted the degrees into radian by using the formula pi(degrees)/180. The gravitational force constant was given to us as 9.8 m/s^2 (g) and with that we were able to calculate the force of the vector by using the equation F=mg. The force was calculated to be .98 N. Then to compute the x and y components you use the formulas Fcos(theata) or Fsin(theta). Those values came out to be x=.98N and y=0N. Next we formed another vector on the force table by added the same amount of mass to the mass holder but this time the mass was placed at 120 degrees. We followed the same procedure as mentioned above the find the force and the x,y components for this vector. The force had a value of .98N and the x and y components were -.49N and .849N
