Energy transformations can be observed in everyday life in activities such as cooking food (electrical energy to heat energy), driving a car (chemical energy to kinetic energy), using a cell phone (electrical energy to sound and light energy), and turning on a flashlight (chemical energy to light energy).
In most energy transformations, part of the energy is wasted. Much of the wasted energy is usually converted to heat.
1. when a toaster transforms electrical energy to thermal energu to toast your bread. 2. a cell phone transforms the electrical energy to eletromagnetic energy to contact with other cellphones. hope you understand it:)
The byproduct of energy transformations is heat, which is released into the environment. This is due to the second law of thermodynamics, which states that some energy will always be converted into an unusable form (in this case, heat) during energy transformations.
Electrical energy to kinetic energy
from electrical energy to mechanical energy
There are a few energy transformations when a gun is fired. Some of these include potential to kinetic energy, chemical to mechanical energy, and chemical to electromagnetic energy.
Kinetic and potential energy are common types of energy involved in energy transformations. Kinetic energy is associated with the motion of objects, while potential energy is associated with the position or state of an object. These energies can be converted from one form to another during energy transformations.
During energy transformations, energy is never created or destroyed, but it can change from one form to another (e.g., thermal to mechanical).
electrical energy to thermal(heat) energy
chemical to light to heat energy :)
