When a moving car hits a parked car and causes the parked car to move, energy is transferred from the moving car to the parked car. When you push a book across the table, the energy from your moving arm is transferred from your body to the book, causing the book to move. When kicking a football that is sitting on the ground, energy is transferred from the body to the ball, setting it in motion. kicker’s A fly ball hits a window in a house, shattering the glass. The energy from the ball was transferred to the glass, making it shatter into pieces and fly in various directions. Fingers hitting piano keys transfer energy from the to the keys. player’s hand Potential energy of oil or gas is changed into energy to heat a building. When a bowling ball knocks over pins that had been standing still, energy is transferred These law of conservation of energy examples show how commonplace this physics concept is in everyday life. ( ) To understand and be able to relate with practical electrical concepts and devices, it is necessary to know the origin of the electrical phenomena. Like other forces including gravity, magnetic energy, and thermodynamics, electricity is a naturally occurring force. When force acts upon a body or mass, energy is used. To produce a flow of electricity, force is required. It is called: Electromotive Force The smallest part of an element is the atom. Atoms are made up of smaller particles. The three main subatomic particles: proton, neutron and electron. See figure below.
