Conservation of energy and transformation of energy. By Paige‚ Stacie‚ Amelia. Objectives Learning about Conservation of energy Learning about transformation of energy Conservation – Preserving a substance. Metabolism Metabolism is a process in which you break down foods into calories and these are combined with oxygen to release the energy that your body needs in order to function/live. This is a very complicated bio-chemical process. Metabolism is essential for the energy for these functions:

ENERGY CONSERVATION IN INDIA INTRODUCTION India has made rapid strides towards economic self-reliance over the last few years. Impressive progress has been made in the fields of industry‚ agriculture‚ communication‚ transport and other sectors necessitating growing consumption of energy for developmental and economic activities. If India is to achieve the targeted growth in GDP‚ it would need commensurate input of energy‚ mainly commercial energy in the form of coal‚ oil‚ gas and electricity.

Energy conservation is a very important part of energy planning and its management. It not only saves energy resources for future‚ avoids wasteful utilisation of energy‚ provides solution to energy crisis and ensures higher per capita availability/ consumption but controls environmental degradation and pollution. New strategy emphasies greater reliance on non-exhaustible and non-conventional sources of energy so as to conserve exhaustible conventional resources like coal‚ petroleum‚ natural gas

QUESTION( Conservation of Energy) 1. Missy Diwater‚ the former platform diver for the Ringling Brother’s Circus had a kinetic energy of 15 000 J just prior to hitting the bucket of water. If Missy’s mass is 50 kg‚ then what is her speed? Solution: According to energy conservation‚ the kinetic energy at the bottom of the dive (15‚000J) is equal to her gravitational potential energy before the dive. We can use this fact to find her dive height: PE = mgh h = PE/mg = 15‚000J / (50kg)(9.81m/s²)

Energy audit An energy audit is an inspection‚ survey and analysis of energy flows in a building‚ process or system with the objective of understanding the energy dynamics of the system under study. Typically an energy audit is conducted to seek opportunities to reduce the amount of energy input into the system without negatively affecting the output(s). When the object of study is an occupied building then reducing energy consumption while maintaining or improving human comfort‚ health and safety

What is "energy"? Where does it come from? And how do we pay for it? When you learn the answers to these questions‚ you can also learn how to live more efficiently in your home. In this article‚ we ’ll discuss how to be smart about how you use energy‚ how to know when to turn electrical power on and off‚ and how to use natural gas‚ propane‚ and fuel oil in the most effective way. Basic Concepts of Energy Efficiency You can make a lot of progress toward improving the energy efficiency in your

Maggie Haas Reiter Honors Physic 8 March 2015 Background Information: Anything that has mass and is moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved‚ which means that “momentum before an event equals momentum immediately after‚ or pi=pf”. Since pi=pf‚ then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi)

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis
