When an object is moving or can move, Mechanical Energy can be described as the energy of movement. It’s the total of potential and kinetic energy in physical science.
A wrecking ball:
Wrecking balls are enormous, round objects used in the deconstruction of structures. After being raised to a given height, the ball gains potential energy, converted into kinetic energy when it descends. This cycle is re-enacted over and over again without interruption. As soon as the wrecking ball hits the target, it is applied, resulting in the demolition of buildings.
Hammer:
For example, when we use a hammer to drive a nail into a wall, we are using force. We are merely utilizing the hammer to impart some force on the nail, resulting in some work. An object at rest does not have any moving parts but does have some stored energy in the form of potential energy. 
Kinetic energy is at play when we swing a hammer up to a distance from a nail before striking it. The hammer’s will drive the nail into the wall, which combines kinetic and potential energy. We can also say that the hammer’s force delivered to the nail is Mechanical Energy, total potential, and kinetic energy.
Gun with Darts:
For a dart gun to function properly, we must first grasp how elastic potential energy works. It is possible to fire darts with a spring constructed from elastic potential energy that has been saved. When the darts are inserted into a dart gun, the spring in the gun compresses. At that time, the dart gun is composed entirely of elastic potential energy. The spring is able to exert force on the dart and do labor, such as shifting the dart, because of the energy stored in the spring.
An example of a windmill:
Windmills and turbines are used to generate electricity, which is subsequently distributed to our homes. It is mechanical power and labor that propels them forward. Kinetic energy is a type of energy that can be found in the movement of air.
Because of this energy, the fan’s blades are able to provide useful work. It is the force imposed on the blades by moving air that causes them to revolve. Fan blades could be pushed by the wind if it was able to harness from the wind.
Balls for Bowling:
Target shooting is a fun sport that serves as a good demonstration of Mechanical Energy in motion as well as the use of the object that holds it. It is this type of energy that is released by a bowling ball as it goes towards the pins that is known as kinetic energy. The ball is able to apply force on the pins because of its energy.
When the ball strikes these pins, they are shifted, necessitating the need for more labor to be performed. Because the bowling ball was able to displace the pins, we can infer that it was responsible for the ball’s ability to perform work on them when it struck them.
Hydroelectric Power Plant:
Hydropower facilities use moving water to create electricity. The hydropower plants serve as a great illustration of how to accomplish tasks. We are frequently treated to the sight of rushing water as it makes its way down a slope in a hydropower plant. To maximize the quantity of gravitational potential energy and kinetic energy present in the flowing water, it is hurled from tremendous heights.
After hitting the turbine blades at the waterfall’s base, water cascades down the slope and into the reservoir below. Rotation is possible because of the water’s energy, allowing it to work on the blades. Turbines transform from water into electrical power as soon as the turbine blades move. The ability of water to work on the turbine blades results.
Cycling:
The chemical potential energy of a person riding a bicycle is an energy source. The biker uses this energy to work on the bicycle’s paddles by exerting some power and allowing the bike to move forward.
Moon:
All seven planets revolve around the sun, but only one natural satellite, the Moon, revolves around the Earth. Since it circles the Earth, the Moon has both potential and kinetic energy that can harness it. As a result of the Moon’s position and motion, we may conclude that it has a high content in the form of potential and kinetic energy. Following the conservation, the Mechanical Energy of the Earth-Moon system remains constant.
In the absence of any external forces other than gravitational attraction operating on a closed system, this equation states that the security system will remain constant. Since there is no friction or air resistance in space, the Earth-Moon system remains constant with the cyclical interchange of kinetic and potential energy at different times of the month.
Electricity:
Electric motors are used in most domestic appliances, such as vacuum cleaners, blenders, and washing machines. An electric motor is a device capable of converting electrical energy and vice versa in a single operation. When we turn on our ceiling fan, electrical energy is turned into Mechanical Energy. Therefore, we can say that the electric motor energy into work done on the blades.
Arrows and Bow:
Another illustration can be found in the form of a bow and arrow. Arrows have elastic potential energy while they’re drawn, which is released when they’re released. The arrow is propelled by the kinetic energy generated by the bow’s pull. The combination of these two energies provides the arrow’s mechanical point. That’s because it used Mechanical Energy to change a target’s state, which in turn altered the target’s state.
