When an object (stone‚ spear‚ arrow or bullet) is thrown‚ hurled or shot in the air‚ the object is a PROJECTILE (“Projectile”). The study of projectile is important because it must be realized that they are very much part of man’s daily life then and now. Whether man likes it or not‚ he encounters and uses projectile in his everyday life. Our hunting ancestors threw stones and spears on animals to kill them for their food. In today’s sports‚ balls follow projectile motion such

Part one: The Lab 1. You will be helping Galileo perform the experiment to determine if objects with different mass fall at the same‚ or different‚ rates in the air and in a vacuum. Before you conduct your experiment‚ you need to form a hypothesis. A hypothesis is a prediction of what you think will happen in the experiment. The hypothesis is a statement that describes “if” a certain set of circumstances are present “then” there will be a specific result that will occur. Record your hypothesis

TEST TO EXAMINE THE PROPERTIES AND THE RATE OF SETTLEMENT OF PURE KAOLINITE CLAY BY USING OEDOMETER IN 1-DIMENSIONAL CONSOLIDATION Abstract The aim of this experiment was to explain how to use two type of oedometer to calculate compression index (Cc) and re-compression index (Cr)‚ measuring the pre-consilidation (s’vc)‚ and to predict the coefficient of consolidation (Cv). The soil used in this experiment is Kaolinite clay‚ which has Cv = 8.69 sqm/year at 300 kPa (hydraulic

L2_Basic Component of soil Weight-Volume Relationships Prepared by: aidsalma@feng.unimas.my 1 Introduction • Soil is a three-phase material consisting of a skeleton of solid particles. • The solid particles encompassing voids filled with water & air. • It is necessary that the constitution of the solidswater-air mixture can be expressed quantitatively in terms of some standard physical properties. • Soil water is commonly known as pore water • If all voids are filled with water = soil

Experiment 2: Kinematics of Human Motion Abstract: Kinematics is the branch of classical mechanics that describes the motion of bodies (objects) and systems (groups of objects) without consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis of human motion‚ where displacement vs time and velocity vs. time were graphed. Graphical analysis of motion where in the 10th seconds the total displacement is 18.75m‚ average velocity
