Hoo Sze Yen Form 4 Experiments Physics SPM 2008 CHAPTER 1: INTRODUCTION TO PHYSICS 1.1 PENDULUM Hypothesis: The longer the length of a simple pendulum‚ the longer the period of oscillation. Aim of the experiment: To investigate how the period of a simple pendulum varies with its length. Variables: Manipulated: The length of the pendulum‚ l Responding: The period of the pendulum‚ T Constant: The mass of the pendulum bob‚ gravitational acceleration Apparatus/Materials: Pendulum bob‚ length

Madeline Totten Dr. Su Phy 110 Lab 18 September 2013 Lab 2: Introduction to DataStudio Purpose: The purpose of this lab is to practice designing an experiment by choosing the variables‚ using DataStudio to collect the data from the experiment‚ and then taking our data and presenting it and our results in a report. Method: For this experiment‚ the goal was to use a simple pendulum (shown to the left) to measure the period of the motion. For task 1‚ we just became familiar with DataStudio

PHYSICS INTERNAL ASSESSMENT How to measure the density of water using graphical method? Name: Chia Yee Xin Candidate Number: Session: October 2014 School: Sri KDU International School Research Question: To measure the density of water using graphical method. Introduction: Water is the most abundant compound on the Earth and it covers about 70% of the Earth’s surface. Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of

Introduction: The purpose of this lab is to see how the colour of an apple would change (browning) over time‚ when placed in different conditions. When referring to the term “browning”‚ it is meant to imply the change of colour that occurs inside the apple‚ giving an appearance that is distasteful (Di Guardo et al.‚ 2013). Specifically‚ within this lab the apple was cut into 4 pieces with 3 pieces being placed on a weigh boat‚ and a 4th piece placed in a beaker of water. These weigh boats were

Engineering B45 Concrete Lab Report Introduction: Concrete is a mixture of sand and rock or similar inert material (aggregates) held together by a cementing material. Usually the cementing material is Portland cement‚ but sometimes binders such as asphalt or gypsum are used‚ in which case the concrete may be called asphaltic concrete or gypsum concrete. Properties of concrete are governed not only by the properties of its ingredients (cement‚ water‚ sand‚ and coarse aggregate) but also‚ to a great

Introduction In this lab‚ the purpose was to verify Hess’s Law. Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The enthalpy of reaction‚ ΔHrxn is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant pressure in the reaction. The change represents the difference in enthalpy of the products and the reactants and is independent of the steps

The objective of this lab was to recreate the color profile of a given solution. In this case‚ the solution was Powerade. The final solution should match the absorbance values at the peak wavelengths (420nm and 628nm) in Powerade. This lab was done using deionized water‚ FD&C Blue #1‚ FD&C Yellow #5‚ FD&C Red #40‚ and a spectrometer. To obtain the correct color profile‚ FD&C Blue #1 and FD&C Yellow #5 were utilized in the sample solutions. The experiment was conducted over two days; the first day
