Today in physics class we did a lab on centripetal force.
In this lab the equipment that we needed was
glass tube 10 to 20 cm long, and about 1 cm outside diameter (tube should be fire-polished at both ends)
Nylon cord (about 1.5 m) size 4 stopper, 2hole 25 iron washers (about 0.06n each)
Stopwatch or watch with second hand
Alligator clip
The objective of the lab was
During this investigation you will study circular motion experimentally. Use the graphical analysis of circular motion to study the relationships between the centripetal force and the velocity of an object moving in a circular path and the radius of the path.
In the lab we had to connect a rubber stopper to one end of the string and on the other end we had to add a bent paper clip with washers connected to it you also need to put the alligator clips somewhere near the middle of the string.
We also had to time how many seconds it would take to get 30 revolutions for 5 washers, 10 washers, 15 washers, 20 washers and 25 washers.
Don't forget to do the calculations and the Interpretation on the sheet. Well that's all the next scribe will be ZEPH.
