KINETIC ENERGY Objects have energy because of their motion; this energy is called kinetic energy. Kinetic energy of the objects having mass m and velocity v can be calculated with the formula given below; K=1/2mv² Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity‚ acceleration‚ force‚ and momentum‚ the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy‚ the standard metric unit of measurement for kinetic energy is

Energy is essential part of this world. Everything in the world runs on energy. It play‚s important part in development of a country. it is considered to be life line of any economy and most vital instrument of socioeconomic development of a country. There are many types of energy in this world which are obtained from different sources‚ But in Pakistan main sources of energy are (fossil fules‚ petroleum products‚ natural gas‚ coal‚ wind‚ nuclear‚ hydro power) Pakistan is

Heat energy Temperature – measure of the average KE of the particles in a substance‚ measured in degrees Celsius or degrees Kelvin. Celsius 0⁰C (freezing point of water) to 100⁰C (boiling point of water) Kelvin 0 K (absolute zero‚ particles stop moving theoretically)‚ equivalent to -273.15⁰C. Uses the same scale for increase‚ ie. a 1⁰C increase in temperature equates to a 1K increase in temperature. Heat – amount of energy transferred‚ measured in Joules (J) Kinetic Energy‚ Thermal

Associate Program Material Cell Energy Worksheet Answer the following questions: Cellular respiration: • What is cellular respiration and what are its three stages? Cellular respiration is the process that breaks down food to use as energy. The three main stages are glycolysis‚ citric acid cycle‚ and electron transport (Simon‚ Reece‚ & Dickey‚ 2010). • What is the role of glycolysis? Include the reactants and the products. Where does it occur? During glycolysis‚ a team

Energy Crisis in Pakistan ‘Crisis’ has been coined by a Greek word which means ‘decisive moment’. Crisis is declared when something has gone to a level where an action must be taken to avoid complete disaster or breakdown. ‘Energy Crisis’ happens due to several reasons‚ some of which are: misallocation of resources‚ incompetency of exploration sector‚ increasing price of oil in international market‚ power wastage‚ less dams‚ little deployment of unconventional energy resources‚ etc. Energy

History of Solar Energy 1767‚ First Solar Collector In the year 1767 a Swiss scientist named Horace-Benedict de Saussure created the first solar collector – an insulated box covered with three layers of glass to absorb heat energy. Saussure’s box became widely known as the first solar oven‚ reaching temperatures of 230 degrees fahrenheit. 1839‚ Photovolataic Effect Defined In 1839 a major milestone in the evolution of solar energy happened with the defining of the photovoltaic effect.

Nuclear Energy There are many advantages and disadvantages of using nuclear power. Nuclear power is said to prevent power outages that happen in areas without nuclear power. For an example‚ if we were using hydroelectricity and the dam suddenly malfunctions‚ then we won’t have electricity until someone fixes the dam‚ and that would be difficult if it happened in the middle of the night. However‚ on the other hand‚ nuclear power is also considered toxic and it pollutes the Earth with harmful and
