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.Continue Reading
Mechanical energy can be either potential or kinetic. Potential energy, or PE, is the energy something has because of its position, instead of its actual motion. An example of something with potential energy is a coiled spring, a charged battery or a raised weight. There are two types of potential energy, gravitational and elastic. Gravitational is relates to the energy from an object in relation to its vertical position above the ground. Elastic energy refers to the object's energy from a stretched position.
Kinetic energy, or KE, is the energy of motion. Examples of things with kinetic energy are an airplane as it flies through the air, a baseball after it is thrown by the pitcher or a car driving down the road.
In order to find an object's total mechanical energy, or TME, the formula one uses is TME = PE + KE. However, since there are two types of potential energy, the formula can be expanded to TME = PEgrav + PEspring + KE.Learn more about Motion & Mechanics
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 >
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.Full Answer >
The lever class of a hammer depends upon its use. If the hammer is used as a claw to remove a nail, it is a first class lever. When the hammer is used to strike a nail, it is a third class lever.Full Answer >
Two examples of third-class levers are a hammer driving a nail and the human forearm. In third-class levers, the effort is placed between the load and the fulcrum.Full Answer >
