used to solve problems that involve groups where each group has the same number of objects. For example: Joe has 5 friends‚ and each of his friends has 5 marbles. How many marbles does Joe’s friends have? To solve this problem‚ you can draw it out as 5 different groups and each group has five marbles each. Answer: Joe’s friends have 25 marbles all together. -Number lines can be used to solve multiplication problems by skip hopping to the number you are multiplying and then the number of hops

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

GS104 Lab Report Experiment # 2 Data Collection David Case: January 23‚ 2015 Experiment #2 Data Collection Objectives: Exercise 1: Formulating a Hypothesis about pitching speed. To form a hypothesis for the pitching velocity of a ball. Use a spreadsheet and math to calculate the actual velocity and determine the accuracy of the hypothesis. I will also roll a large ball to measure its velocity and graph its horizontal motion. Materials: Volley

velocity and time b) To determine the acceleration of the motion of the trolley c) To find the constant force exerted on the trolley Introduction: Newton ’s second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon

Uniform Acceleration Cedric C. Labasan Physics Department‚ De La Salle University St. Joseph Hall Room 404‚ 2401‚ Taft Avenue‚ Manila‚ Philippines cedric_labasan@dlsu.ph Abstract This lab report defines what uniform acceleration is and how to calculate uniform acceleration of a cart rolling down a ramp at different angles and elevations. The experiment will be performed by setting the cart on the track against the end stop and then record this final position on the steel ramp ten times

and vice-versa. The first of these is the slider-crank - a mechanism widely used in engines to convert the linear thrust of the pistons into useful rotary motion. In this lab we will measure the acceleration of the piston of a lawn mower engine at various speeds. The results exemplify a simple relation between speed and acceleration for kinematically restricted motions‚ which will discover. An adjustable slider-crank apparatus and a computer simulation will show you some effects of changing the proportions
