PHY131L REPORT – Vectors
Objectives
1.
To apply magnitude and direction of vectors in real life situations
Equipment
Force table
Four pulleys
Metal ring
Four weight hangers
String
Two slotted weight sets
Small weight set
Protractor
Ruler
Procedure
Using the force table, we mounted 240g on the 0 degree mark, 150g on 60 degree
mark. Then we tried to put a third weight that would cancel out these two vectors, by trial
and error. Using strings and pulleys, we tried to minimize the effect of friction string had on
the force table. Also, we put a ring in the middle of the table to tie the string to see when
the vectors cancel. If the ring ends up perfectly in the middle, the vectors have cancelled
out.
After the first trial and error experiment, this time, we tried to predict the equilibrant
vector. We mounted 160g on 0’, 200g on 90’, 250g on 200’. We graphed these vectors out,
and then added them together to find a sum of three vectors. By adding 180’ to the sum of
the vectors, we found the equilibrant vector to cancel out all three vectors. Also, we
