A common example of energy transfer that we see in everyday life is the transfer of kinetic energy —the energy associated with motion—from one moving object to a stationary object via work. In physics, work is a measure of energy transfer and refers to the force applied by an object over a distance.
Energy transfer, the change of energy from one form to another. According to the first law of thermodynamics, energy can be neither created nor destroyed; in other words, the total energy of the universe remains constant.
The following are real life examples of how energy transfers: - Sound energy is transferred into electrical when people use microphones. - When the light switch is turned on the electrical energy...
A common example of energy transfer is the transfer of kinetic energy —the energy of motion—from a moving object to a stationary object. When a golf club is swung and hits a golf ball, some of the club's kinetic energy transfers to the ball.
Energy, or the power to do work, cannot be created or destroyed. However, energy can change form. It can also move between objects. A common example of energy moving between objects, called energy transfer, is the transfer of kinetic energy from a moving object to a motionless object. Kinetic energy is the energy of motion.
There are three main types of energy transfer: conduction, convection, and radiation. Conduction is the transfer of heat or electricity through a substance without the movement of the substance itself. This type of energy transfer occurs when two objects are in contact with each other.
A pendulum is a simple example of energy transfer. Beginning at position A, the pendulum fob is not moving. It has some energy because of its height (h) – called gravitational potential energy.
Energy transformation happens when energy is converted into another form. There are many examples of energy transformations in our daily life. A toaster uses the electrical energy running through its wires to create thermal energy —heat—to toast a bagel.

Energy can be transferred from one store to another in four ways: Mechanical work – a force is applied to move an object, for example when a person lifts a book onto a high shelf.
