What is mechanical energy for kids?
Mechanical energy is the moving energy (kinetic energy) of an object plus that object's stored energy (potential energy). The mechanical energy of the pendulum toy shown here includes the kinetic energy of the balls in motion plus the potential energy of the balls that are still.
Does a TV use mechanical energy?
A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.
What kind of energy is toaster?
electrical energyPhoto: An electric toaster takes in electrical energy from the power outlet and converts it into heat, very efficiently. If you want your toast to cook quickly, you need a toaster that radiates as much heat as possible each second onto your bread.
What type of energy is a flashlight?
In a flashlight, the electrical energy becomes light energy and thermal energy in the bulb. 6 Light energy is transported by wave motion. In other words, light is a form of energy caused by electromagnetic waves.

What is mechanical energy?
Mechanical energy can be termed as the energy of movement; as it is found in objects that are moving or have the potential to move. In physical science, it is the sum of potential energy and kinetic energy. The formula for mechanical energy is; Mechanical energy = kinetic energy + Potential energy.
Why is the mechanical energy of the Earth-Moon system constant?
The mechanical energy of the Earth-Moon system remains constant due to the law of conservation of mechanical energy. As explained earlier, this law says that the mechanical energy of a closed system remains constant if there is no external force applied to it, except for the gravitational force.
What is the force applied by a hammer to drive a nail into the wall?
Whenever we use a hammer to, let’s say, hit a nail and drive it into the wall, we are simply applying some force on the nail with the help of the hammer which is causing some work to be done. At rest, a hammer does not contain any kinetic energy but only some amount of potential energy. When we swing a hammer up to some distance from the nail before hitting it, kinetic energy comes into play, and the combination of kinetic energy and potential energy in the hammer, called mechanical energy, will cause the driving of the nail into the wall. Or, we can say that the force applied by the hammer to do work on the nail is mechanical energy, which is the sum of potential and kinetic energy.
How does wind energy work?
Windmills are the structures that convert wind energy into electrical energy and this energy is then supplied to our homes. But from where does this energy in the wind comes and moves the large blades of a windmill? Windmills run on the principle of mechanical energy and work. Moving air (wind) possesses some amount of energy in the form of kinetic energy (due to motion). This energy gives the air the ability to do work on the blades of the fan. The moving air applies force on the blades and enables the work to be done, hence, resulting in their rotation. Therefore, the mechanical energy gave wind the ability to do work on the blades of the fan.
What energy is used to drive a nail into a wall?
When we swing a hammer up to some distance from the nail before hitting it, kinetic energy comes into play, and the combination of kinetic energy and potential energy in the hammer, called mechanical energy, will cause the driving of the nail into the wall.
What is windmill energy?
Windmills run on the principle of mechanical energy and work. Moving air (wind) possesses some amount of energy in the form of kinetic energy (due to motion). This energy gives the air the ability to do work on the blades of the fan.
How is electricity generated in hydropower plants?
In hydropower plants, electricity is generated with the help of running water. The hydropower plants display an excellent example of the use of mechanical energy to do work. In a hydropower plant, we often get to see the view of water running down the slope at an enormous speed. The running water is thrown from a great height just to gain a good amount of energy that is present in the form of gravitational potential energy (due to height) and kinetic energy (due to motion). The water falling down the slope then hits the blades of the turbines, which are installed at the bottom of the waterfall. The mechanical energy of the water enables it to do work on the blades; resulting in their rotation. Once the blades move, the turbine converts the mechanical energy of the water into electrical energy. Hence, mechanical energy gives water the ability to do work on the blades of the turbine.
