Introduction: In physics‚ velocity is often defined as the speed. Gravity is the amount of force that acts upon an object. In this experiment‚ when one projects an object in the air‚ gravity acts upon the object causing it to come down. However‚ the answer that I am trying to discover is if the weight of the object affects the velocity of the object when it comes back to the surface of the earth.

Module 2 Mass Spectroscopy [pic] [pic] Diagram of a mass spectrometer Stage 1: Ionisation The sample is injected as a vapour and the atoms are bombarded by fast moving electrons. This causes the molecule to fragment into two or more pieces. When a molecule or part thereof fragments‚ one portion would be positively charged while the second portion will be uncharged. All uncharged fragments are ultimately lost in the machine as mass spectrometers only work with positive ions. Stage 2: Acceleration

Experiment 1 mass determinations Objective: The purpose of this experiment is to see the difference of precision of different balances. When doing experiments we determine the mass my measuring the sample with a balance. There are many kinds of balances that measure to different precisions. This experiment shows the different results that two balances can give. Summary of Procedures Determine the mass with the triple beam scale to the most precise measurement possible for the scale.

anyone wanting to learn Algebra or needing a refresher for algebra. I’ve tried to make the notes as self contained as possible and do not reference any book. However‚ they do assume that you’ve had some exposure to the basics of algebra at some point prior to this. While there is some review of exponents‚ factoring and graphing it is assumed that not a lot of review will be needed to remind you how these topics work. Here are a couple of warnings to my students who may be here to get a
