When a light switch is turned on, electrical energy runs through the wires and is transferred to the bulb where electrical energy is converted to light and heat energy. This is an example of energy transfer. When a bowling ball that has kinetic energy strikes the bowling pins which are stationary, energy is transferred from the ball to the pins, causing the pins to move.Know More
Energy can be neither created nor destroyed, according to the law of conservation of energy, but it can change from one form to another or transfer from one object to another. A rock placed on a tall cliff has potential energy due to the height at which it is placed. If the rock starts to fall, its potential energy is changed to kinetic energy since the rock traded in the height of its position for velocity of its movement.
Electrical energy is changed to kinetic energy when a fan is turned on. Chemical energy of food is changed to mechanical energy whenever organisms do work. Batteries convert chemical energy to electrical energy to power various devices. Electric generators convert the chemical energy of gasoline to kinetic energy to move a coil of wire relative to a magnet to generate electrical energy. When a stationary book on a table is pushed, energy from the person pushing it is transferred to the book, causing the book to move. When striking a drum, the kinetic energy of the stick changes to sound energy.Learn more about Motion & Mechanics
Electrical energy and gravitational potential energy are two examples of stored energy. Energy can be stored or transferred. Energy that moves between or among places is referred to as kinetic energy, while energy that accumulates in single sources is called stored energy or potential energy.Full Answer >
Examples of elastic potential energy include a rubber band, spring, bouncing ball, catapult, bungee cord, bow string and trampoline. Elastic potential energy is stored in these objects when they are pulled, stretched or compressed. This energy becomes kinetic energy when these objects return to their original shape. For instance, a compressed spring has elastic potential energy until the coils return to their original alignment and push other objects away.Full Answer >
Everything that moves has kinetic energy. The wind causing things such as leaves and branches to move and moving water are two examples of kinetic energy for kids.Full Answer >
Some examples of mechanical energy are a hammer, a bowling ball, a drawn bow and arrow and a moving volleyball. Mechanical energy is defined as the energy an object has either due to its motion or its stored energy of position.Full Answer >
