Experiment 4: Work‚ Power and Energy Maria Isabela Mendoza‚ Carmela Miranda‚ Arianne Nagrampa‚ and Vivien Oreo Department of Biological Sciences University of Santo Tomas España‚ Manila‚ Philippines Abstract The experiment performed involved work‚ power and energy. On the first activity‚ the time it took for each member to go up and down the stairs was recorded. Afterwards‚ the work and power done were computed. The most powerful member in the group was student number 2 with power outputs of 239

POTENTIAL ENERGY DIAGRAM In physics the terms of mechanical energy usually refers to Potential energy (U) and Kinetic Energy (K). In the absence of non-conservative‚ or dissipative forces‚ these energies obey the law of conservation of energy‚ or ΔU + ΔK = 0. That is‚ when a system is only acting under the influence of conservative forces its total energy content never changes‚ the energy just converts between forms. At any point in the cycle‚ the total energy is constant‚ U + K = Umax = Kmax

Description The soft drink industry is concentrated with the three major players‚ Coca-Cola Co.‚ PepsiCo Inc.‚ and Cadbury Schweppes Plc.‚ making up 90 percent of the $52 billion dollar a year domestic soft drink market (Santa‚ 1996). The soft drink market is a relatively mature market with annual growth of 4-5% causing intense rivalry among brands for market share and growth (Crouch‚ Steve). This paper will explore Porter ’s Five Forces to

ENERGY: Energy is the amount of force or power when applied can move one object from one position to another or Energy defines the capacity of a system to do work. Energy exists in everybody whether they are human beings or animals or non-living things for e.g.: Jet‚ Light‚ Machines etc... Energy can have many forms: kinetic‚ potential‚ light‚ sound‚ gravitational‚ elastic‚ electromagnetic or nuclear. The many different natural and renewable energy technologies are by no means breakthrough. Many

Work and Energy Worksheet Section 1 Work: 1. A person pulls a toboggan for a distance of 35.0m along the snow. The force in the rope (tension) is 94.0N. How much work is done on the sled? Solution: W= Fd W= 94.0N x 35.0m W= 3290 Nm or J 2. The cable of a large crane applies a force of 2.2x10^4N to a demolition ball as it lifts it vertically a distance of 7.6m. a) How much work is done on the ball? b) Is the work positive or negative? Why? Solution:

Calories: The name calorie is used for two units of energy. Although these units are part of the metric system‚ they have been superseded in the International System of Units by the joule. One small calorie is approximately 4.2 joules. Calories are also most known to be used in foods and diet‚ which is key to athletes. Joules: A Joule is equal to the energy transferred to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. Kilocalories:
