What type of energy transformation takes place when you walk?
the answer is : Chemical energy is being converted into mechanical energy.
Battery (chemical energy) goes to the wires (electrical energy) which goes to the light bulb (thermal and electromagnetic energy. In the bulb of a traditional flashlight, electric current energy is transformed to heat and then partially to light, when the temperature of the filament in the bulb is sufficient. In an LED type flashlight, little heat is produced and more of the electrical current energy is transformed into light.
When one type of energy is transformed into another type of energy during a conversion what is lost to the environment?
Usually any energy system uses or produces heat energy, often by friction or by direct transfer. When writing your body is converting chemical energy into mechanical energy in the act of movement. By exerting, or using energy your body also produces excess heat, in a very small amount, which it then has to dissipate by perspiration. The friction of the pencil tip on the paper also produces a tiny amount of heat energy, and finally…
