examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters

Flemister Renewable Energy is best America’s dependency on foreign oil is costing us more than just money; it costs us our clean air and potentially thousands of jobs in America. Our nation needs to create its own renewable energy. The dependency on other countries is crippling our economy. Drilling for oil in the United States is not the answer. We need to take better care of our planet and that each of us must

Experiment 4.5 Measuring the energy content of a “Dorito” and Popcorn. Using the method as described on page 46 of the textbook‚ measure the energy content of a Dorito and a “Popped” corn kernel. Aim: 1. Compare your results of each food and determine which will give the greatest energy per gram. 2. How much of each food would you need to boil 250mL of water? Hypothesis: (Before you begin‚ what do you think will be the conclusion.) As the Dorito is heated‚ it will release much more heat

Energy in food lab report Aim: How much energy there is in food. Hypothesis: If I work out how much the water temperature has risen by burning food underneath water‚ the mass of the water and the mass of food I can work out how much energy was in the food. Introduction: This experiment is about how much energy there is in food. There are a few different types of energy‚ the one we are looking at is chemical energy. Some other types of energy are: thermal energy which is heat‚ magnetic energy which

Light consist of very less amount of mass that it could not be measured. This paper is based on the concept that when the mass of light is increased it can move the objects. So‚ the light with increased mass can be used in many applications in practical life such as producing electricity. Increase
