February 25‚ 2013 Lab: Equilibrium of Forces Purpose/Objective: The objective of this lab was to test the first condition of equilibrium for a set of concurrent coplanar forces‚ prove Lami’s Theorem‚ and to determine an unknown mass using rules of equilibrium. Procedure: In the lab‚ we wanted to find at what angles three separate weights would create a net zero force on a force table so that the ring holding the weights was exactly centered in the middle

Physics Lab LR Tuesday 8-9:55 Due 02/26/15 Experiment #1 Free Fall Experiment Abstract In this experiment we studied the motion of an object in free fall‚ that is an object being dropped from a certain height to Earth’s surface. In this experiment we tested the idea that no matter what the size‚ shape‚ color‚ etc. of the object if it would still experience the same constant acceleration throughout its fall (short distance). The constant downward acceleration it experiences is due to Earth’s

Activity 1 – Theories of Ageing Disengagement theory The disengagement theory is one of the first social theories of ageing developed by Cumming and Henry in 1961. It is the idea of which states older people begin to withdraw or disengage from their past roles in society due to the decrease of their physical‚ intellectual and emotional abilities and skills which they are unable to accommodate in their roles. Also‚ at this stage of life‚ the elderly will eventually begin to diminish interests in activities

national and global scale Tourism is the world’s largest and fasted growing economic activity. It consists of a multitude of both positive and negative impacts on people’s lives and the biophysical environment. A suitable balance must be established between the environmental‚ social and economic impacts of tourism in order to ensure its long-term sustainability and in prosperity as a mutually beneficial economic activity on a global and national scale. Achieving sustainable tourism is a continuous process

advocates of immediate change in industrial emissions‚ and those who believe that the increased temperature is a natural phenomenon. Advocates of immediate change believe that sudden changes in the earth’s climate can be attributed to human activities. Human made commodities such at power plants‚ factories and cars produce toxic emissions that are released into the air‚ causing harm to the environment. Scientist have done much research and are certain that if nothing is done to reduce the waste

affecting student ability in using English in communication. Communicative activities were introduced as the one which brings the language to life by providing a REAL BASIS for speaking‚ and the interactive EXCHANGE of ideas‚ opinions‚ and feelings with another person. It can be seen as an effective method in teaching and learning English. English language learners get beneficial effect from them. With communicative activities‚ learners are really involved in the process and provided chances to experience

Extracurricular activities are a controversial subject among many school districts around the United States. Many believe that education and funding are more important matters than clubs and sports. Extracurricular activities should not be eliminated throughout school districts due to funding. School is important. Everyone knows this and no one can truly argue against it. Wake up‚ go to school‚ come home and repeat. But why do people do this? Why do we attend school everyday? Most would say

force on the projectile is gravity. With gravity being a presence and a factor in our everyday lives and in this experiment‚ gravity will push down on the projectile forcing it back down to the ground. For example if someone shot a cannon straight and there was no gravity then the cannon would keep traveling at a constant speed‚ go farther and travel in a straight line. Note this is Newtons first law about motion‚ an object in motion will stay in motion. Now if gravity is involved with the cannon

org/go/Experiment_480.html Pendulum Motion Aim: To determine the rate of acceleration due to gravity by using a pendulum. Background Information: Equation One: T=2πlg Where T = the period of the pendulum (s). This is the time taken for the pendulum to return to its starting position. l = length of the pendulum g = the rate of acceleration due to gravity (ms-2) * In order to find the acceleration due to gravity‚ the equation must be rearranged to look like this‚ and give “g” as the subject:
