Energy transformations are all around us. Let’s get outside to discover examples of energy being transformed and identify the inputs and outputs.
Energy transformations happen when one form of energy (energy input) is changed to another form of energy (energy output).
For example, a lamp changes electrical energy to light energy. Your body changes the chemical energy from food to kinetic energy or motion as you run around.
Energy is the ability or capacity to do work. Energy makes change possible. It is the power or ability to make things happen.
Energy is all around us. The 10 forms of energy are listed below:
The law of conservation of energy states that energy cannot be created or destroyed but can be changed. When something happens, energy is transformed from one form to another. The energy input is the energy that goes into an object or system and the energy output is the energy that comes out. For example, electrical energy is the energy input to a lamp and light energy is the output. Depending on the light bulb used, thermal/heat energy may also be an energy output.
