Lab 5 Conservation of Momentum and Energy Abstract The physics laws governing conservation of momentum and mechanical energy were investigated by performing multiple experiments with differing conditions. Conservation laws state energy is to be conserved in systems with no net external forces. Two trials consisted of inelastic collisions and two trials consisted of elastic conditions. Photogate software helped decipher initial and final velocities in order

Conservation of Energy Lab Honors Physics December 9‚ 2014 Date Performed: December 5‚2014 Instructor: Mrs. Kelly I. Objective: Calculate the speed of the Bunny on release from the table II. Procedure: 1. Gather All Materials 2. Place the bunny turned in on itself on the ground (this enables the toy to launch itself upward by suction; elastic and potential energy). Do so 5 times 3. Measure the height traveled by the stopper using a meter stick per each trial. 4. Using the measurements

Conservation of Energy In explaining the laws of conservation of energy‚ energy cannot be destroyed or made. Although‚ energy can be transformed or transferred from one form to another‚ for example: The total amount of energy in any system never changes but stays constant over time. Second example: Coal is burned‚ and then used as thermal energy for heat‚ next the steam is used for mechanical energy. Energy is never destroyed but changed to forms like thermal energy‚ gravitational energy‚ electromagnetic

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

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

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

the world go around. To have money; to have lots of it is not wrong and it never will be‚ but money is a tool either for good or for bad. How we use the money is what is of great importance here. It is always better to be rich rather than poor. The reason is simple; to have is better than to lack. We all want our daily needs met. It is human nature and there is nothing wrong with it. It is better to be rich there are a lot of bad things about being poor‚ that being rich could cure‚ collectors

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)
