SI unit: coulomb (C) Quantum of charge: the proton charge (e) the electron charge (-e) e = 6.02 ? 10-19Coulombs Conservation of Charge The net charge in any process or reaction remains unchanged. Coulomb?s Law Calculates magnitude of force between charges Force is repulsive if charges have the same sign. Force is attractive if charges have opposite signs. F = kq1q2/r2 F: force (N) k: constant 9.0 ? 109 N m2/C2 q1, q2: charges (C) r: distance between charge centers (m) NOTE: k = 1/(4??o) where ?o = 8.85? 10-12 C2/ N m2 Multiple Forces on a Charges Ftot = ?

Arnav Sridher Period 2 Physics Collision Investigation Purpose: The purpose of this lab is to investigate the change in total momentum and total kinetic energy of an isolated 2 car collision. Procedure: Go to the website given Set up trial 1 Set a velocity for both cars as well as the mass. Make sure to follow the sheet that says what each trial should include. Press go and record the final velocity for each vehicle Repeat the steps for each trial Once you have 10 trials accounted for, calculate kinetic energy using the equation Ek=1/2(mv2) Once you have done this for the 10 trials, calculate the momentum that each vehicle has using the equation P=mv Data Table: Trials 1-4(elastic), trials 5-8(perfectly inelastic), and trials 9&10(inelastic) M1 (Kg) M2 (Kg) V1 (m/s) V2 (m/s)

Test Questions Two tugboats are moving a barge. Tugboat A exerts a force of 3000 newtons on the barge. Tugboat B exerts a force of 5000 newtons in the same direction. What is the combined force on the barge? 8000 newtons 4000 newtons 2000 newtons None of the above If two men were arm wrestling and the first man was using 15 newtons, while the other was using 10 newtons, who would win? A. Neither B. First Man C. The one using 10 newtons D. The information given is not enough to answer the question What is net force? The amount of matter in an object. How much work is being done?

Density Lab Kiara Soto West Broward High School Mr.White September 11, 2013 II. What is the density of the cork, crayon and 2 unknown metal samples? III. Density is calculated by mass/volume. It can be found for any object or substance. Mass can be calculated from a triple beam balance and Volume from a graduated cylinder. As a liquid changes from gas, to liquid, to solid, it gains density. (n.d.). Retrieved from http://www.howstuffworks.com/dictionary/chemistry-terms/density-info.htm IV. If we test all the objects, the smallest metal object will be the densest. V. Beaker Cork Crayon Graduated Cylinder 2 Unknown metal samples Triple-Beam Balance VI. Gather all materials Measure the mass of each object
