This conversion is achieved by the burning of fuel. It says that the mechanical energy of an object in a closed system remains constant if it is not under the influence of any dissipative force (for example friction, air resistance), except for the gravitational force. Due to this energy, the spring is able to apply force on the dart and does work, i.e., displacement of the dart. Therefore, the mechanical energy gave wind the ability to do work on the blades of the fan. Check out these examples of energy transformation from movement. If something is moving, it is using mechanical energy! This website uses cookies to improve your experience. Due to this energy, the ball has the ability to do work on the pins. Windmills convert mechanical energy to electrical energy in homes. Therefore, we can say that the moon exhibits high mechanical energy in the form of potential energy and kinetic energy due to its position and motion, respectively. Digesting food converts mechanical energy to chemical energy. This causes the pool ball to move and cover some distance before coming to rest. There are also instances when a body has both types of energies simultaneously. The total amount of energy in the Universe thus remains constant. It is an example of conversion of heat energy into mechanical energy. These cookies do not store any personal information. Knowing the kinetic energy formulas, you can compute the energy of a system in motion. At rest, a hammer does not contain any kinetic energy but only some amount of potential energy. Energy can neither be created nor be destroyed. It will have potential energy due to the height of the ball from the ground. Moving air (wind) possesses some amount of energy in the form of kinetic energy (due to motion). But from where does this energy in the wind comes and moves the large blades of a windmill? This energy is utilized by the cyclist to do work on the paddles of the bicycle by applying some force and enabling the bicycle to move forward. Copyright © Science Struck &, Inc. Hence, mechanical energy gives water the ability to do work on the blades of the turbine. A dart gun is another example of mechanical energy observed in everyday life. This process is exact opposite to that of a generator. Here are some examples of ways that different types of energy become mechanical energy. In hydropower plants, electricity is generated with the help of running water. Take a look at these sources of mechanical energy that you’re likely to find in the home. Review the examples of mechanical energy below for where you can see it in your everyday life. Electric motors are present in most of the household gadgets like vacuum cleaners, blenders, washing machines, fans, air conditioners, etc. The rotation of these turbines is used to generate electricity. A power drill converts electrical energy to mechanical energy when plugged in and used. The moving air applies force on the blades and enables the work to be done, hence, resulting in their rotation. This energy, when the spring relaxes, causes the dart to move. Energy is required to do any form of work. A part of this kinetic energy is converted into heat energy and this is the reason why the targets become hot when a bullet strikes them. In addition to mechanical energy, the four types of kinetic energy include: No form of energy can be created or destroyed. Sign up to receive the latest and greatest articles from our site automatically each week (give or take)...right to your inbox. Whereas, kinetic energy is the energy that a system, or a body possesses, owing to its relative motion. Now if the ball were to fall off from the table, the potential energy will begin to convert into kinetic energy. This mechanical energy is in the form of kinetic energy of a locomotive or a vehicle in motion. The kinetic energy of the winds cause the blades to spin. Copyright © 2020 LoveToKnow. Conversions to mechanical energy allow an object to move. Mechanical energy can be used to do work. These cookies will be stored in your browser only with your consent. Energy is required to do any form of work. In every example, it said, “it posses mechanical energy in the form of potential energy”. Some other examples of conservation of mechanical energy are: ■ Releasing a spring after compressing it, ■ Releasing a rubber band that was stretched, ■ A bowling ball striking on bowling pins, ■ A sliding or a rolling object coming to rest. Electrical energy is used in engines where it is converted to mechanical energy. Music converts sound energy to mechanical energy in your eardrum. Check out these examples of objects in a state of inertia, or a list of physical properties of matter or energy. If you are looking for examples of endothermic reactions in everyday life, this article has just what you are looking for.
