I. Introduction: The purpose of this lab report is to differentiate between of Newton’s Third Law and Newton’s Second Law. Newton’s Third Law states that all forces come in pairs and that the two forces in a pair act on different objects and are equal in strength and opposite in direction. Newton’s Second Law states that the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object being accelerated. Using calculation equations for acceleration

Name: Section: SP1L-17 Date: 2/26/11 Coulomb’s Law: What is the charge on a charged pith ball? Experimental Determination of the Electrostatic Force acting between two charged pith balls Equipment: a pvc pipe and fur or wool‚ a metric ruler‚ a protractor‚ two pith balls on a stand as in figure 1. Your teacher will tell you the mass of your pith balls. Procedure: Make sure the strings of your two pith balls are untangled as in figure 1. Make sure that the pith balls are neutral by rubbing

PHYS113 Lab1: Coulomb’s Law ABSTRACT Performing this experimentation will allow one to investigate the relationship quantitative relationship between the electrostatic force and the distance between charged objects. First a simply observation was made of the electrical forces on two pieces of tape taking note of their attraction and repulsion. This same phenomenon was observed in the experimentation of two charged spheres. Furthermore the we used this experimentation to determine the

University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water
