Demonstration--Centripetal Acceleration vs. Angular Frequency
By: Carlos Hernandez
Lab Partners: Dahlia Tran, Ariel De Leon

1. We want to show and understand how Ac=(V^2)/R is related to w=V/R where Ac is Centripetal Acceleration and w is angular speed. Therefore we want to know and understand how the Centripetal force is m*R*w^2
2. We all know and understand how The Force of an object is equal to the mass multiplied by the acceleration . Now we Know the Acceleration for Centripetal force is the equation stated above now we want to understand this, this lab will be done documenting data that the professor gets from the rotating table, there is a block attached to the center of the center by a string from this mechanism we will know the following information, mass of the block(we change it throughout the experiment), Radius in cm, Volts inputted to the system, Time in sec, and the Force gotten by the Force detector attached to the block and the string. The professor did this experiment several times like so; 4 times with the mass of 200g , the radius of those 4 times being, 19cm, 28.5 cm, 40 cm, and 54 cm. the volts for those for times was fixed at 6.1 , and of coarse the time and Force changed for each scenario, a photo with all this data will be below. After those 4 trials the mass stayed the same for the following next 3 trials as will as the radius at 54 cm but the volt input were changed to 6.6 , 7.0 and 7.7. after these 3 trials there was 1 trial done with the mass at 100g, radius 50cm, and volts 7.7, and one last trial with the mass at 50 g radius 54.
