F. Fcos . . s. Work - Transfer of energy. Work = (Force)(Distance) W = Fs cos . F. Fcos . . s. W = Fs cos . Tricky bits : 0 o cos = 1 180 o cos = -1 (examples of positive, negative work).
Energy, Energy Transfer. Working with Energy. Energy. Energy can be neither created nor destroyed , during a process it may change from one form to another but the same amount is present. Forms of Energy. Total Energy includes: Thermal Mechanical Kinetic Potential Electric

Energy Transfer. Energy is “the ability to do work”. Heat and the Earth’s Atmosphere: Radiation. Nearly all the Earth’s energy comes from the Sun Sun: nuclear reactor Earth receives less than one billionth of the Sun’s energy
Energy Transfer. Aditya, Caca, Sammy Grade 8.1. Introduction. Energy transfer is how energy is moved from one place to another A food chain is a description of how energy transfers in an ecosystem from organism to organism by eating each other. Australian Food Chain. primary consumer.
Energy transfer. Lesson 2 – Heat Transfer. Aims: recall that energy transfer may take place by conduction, convection and radiation. describe the role of convection in everyday phenomena. describe how insulation is used to reduce energy transfers from buildings and the human body. HOT COLD.
