Procedure
Accounting For Friction
Because friction is not included in the theory, it will be compensated for friction. When by finding out how much mass over the pulley it takes to overcome kinetic friction. the mass drops at a constant speed, the weight of the mass is equal to the kinetic apparatus.
Then this "friction mass" will be subtracted from the mass used to accelerate the D To find the mass required to overcome kinetic friction, put just enough mass hanging over the pulley so that the velocity is constant. Record this friction mass in Table 1.2. Finding the Acceleration of the Disk 30 g (record the exact hanging mass in Table over the pulley. Wind the thread up and let the mass fall from the table to the floor, timing the fall. 2 Repeat this for a total of 5 times, always starting the hanging mass in the same position. Measure the height that the mass falls and record this height in Table 1.2.
