Experiment 2: Kinematics of Human Motion Laboratory Report Leopoldo Luis A. Gueta‚ Lady Lian Lagamayo‚ Val Ian Caleb Leus‚ Kimberly Anne C. Macarilay Department of Math and Physics College of Science‚ University of Santo Tomas España Street‚ Manila Philippines Abstract Kinematics is the branch of classical mechanics that describes the motion of bodies and systems without consideration of the forces that cause the motion. There are four activities done in this experiment. Graphical analysis

Develop hypotheses predicting the effect of pyrite and coal on the acidity of water? a. Pyrite hypothesis = If pyrite is added to a beaker with 100mL of water‚ then it will reduce the pH over 48 hours. b. Coal hypothesis = It activated carbon is added

Investigating Projectiles Background: A projectile is an entity which only has the force of gravity acting upon it. A projectile can be cast‚ fired‚ flung‚ heaved‚ hurled‚ pitched‚ tossed and thrown. A projectile can be anything as long as it has initial horizontal velocity that is not equal to zero which has the acceleration due to gravity. Projectile motion happens when an object projected with a force stops putting influence on the object after its launched‚ hence the only force being gravity

Lab Report: Projectile MotionChange Launch Angle 03/05/2012 James Allison section 20362 Group 5 James Allison‚ Clint Rowe‚ & William Cochran Objective: In this lab we will compare different parameters of a launched projectile. This includes time of flight‚ initial velocity‚ initial vertical velocity‚ initial horizontal velocity‚ range‚ time of max height. All these data points are collected for 30°‚ 40°‚ 45°‚ 50°

AIMS At the end of the experiment‚ students should be able to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves

Velocity of a Projectile | | | Abhishek Samdaria | Pd.4 and 5 | | Lab #3: Initial Velocity of a Projectile Theory: How can we determine the initial velocity of a projectile? Experimental Design: The purpose behind this experiment was to determine the initial velocity of a projectile. Projection motion consists of kinematics of motion in the x and y directions. With two dimension kinematics‚ there are the x and y components in any given velocity. In projectile motion‚ the x component

PROJECTILE MOTION PRACTICE QUESTIONS (WITH ANSWERS) * challenge questions Q1. A golfer practising on a range with an elevated tee 4.9 m above the fairway is able to strike a ball so that it leaves the club with a horizontal velocity of 20 m s–1. (Assume the acceleration due to gravity is 9.80 m s–2‚ and the effects of air resistance may be ignored unless otherwise stated.) a b c d e How long after the ball leaves the club will it land on the fairway? What horizontal distance will the ball travel
