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

FREE FALL AND CONSERVATION OF MECHANICAL ENERGY ABSTRACT Free fall is defined as the ideal falling motion of an object that is subject only to the earth’s gravitational field. To prove the law of conservation of energy‚ the free fall motion of an object can be represented through 3 different analyses; position of the object vs. time‚ velocity of the object vs. time‚ and acceleration of the object vs. time. It is observed in this ball toss experiment‚ at any point during the free fall period‚

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 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

The electric car is a vehicle that uses electric power and there are many applications to design and one of these applications is replacing the original engine of the car and put an electric motor position is the easiest way to switch from oil to electricity while maintaining the other components of the car and is provided with the power required by batteries storage power. The design of the electric car is based on an electric motor‚ an electric control system‚ and a powerful battery can be recharged
