# Potential Energy: The Law Of Conservation Of Energy

1201 Words 5 Pages
Energy is a property of objects that can be converted in plenty of different forms or be transferred to another objects. Energy comes in these different forms that may seem different, but they all amount to the same thing. Energy is one of the true constants of universe because as long as the universe has been existent, energy was existent. Due to it being a true constant energy can never be created or destroyed, this is called the law of conservation of energy. This law states that the total energy in an isolated system remains constant, meaning that no energy can be gained or loosed but changed from one form to the other. For example a human subject would eat an apple for sustenance for breakfast, the subject’s body would transform that apple …show more content…
Exploring how machines utilizes a plethora of different types of energy forms, one could see how energy is used every day, and is in everything. Potential energy is stored energy as the result of its position. When an object is altered from its usual equilibrium position or is elevated over a relative position, the object is able to store energy by virtue of its position. For example, if a person has a bow in his hand and the string is at its normal state, it has zero potential energy. Once the string is drawn, the bow stores energy or builds potential energy relative to its equilibrium state or when the bow is at rest. For this type of electricity generate there is a specific type of potential energy that needs to be focused on, gravitational potential energy. Hydroelectricity is electricity generated from the movement of water. This renewable resource can come from dams to rivers. How it works is that a dam is built in or to stop the flow of water, the water is elevated giving it gravitational potential energy relative to the sea level. The dam contains shafts in which water is able to …show more content…
Light is electromagnetic radiation within a specific section on the electromagnetic spectrum. Light is just was visible to the human eye. With that said, radiant energy is the energy of gravitational and electromagnetic radiation. And when EM waves are absorbed by object it turns into heat, therefore when radiant energy is absorbed it’s converted into thermal energy. Focusing on solar-powered electricity one could how the energy is transformed and transferred through the system. Solar-powered electricity is just how it is said, electricity generated from exposure to sunlight. Using solar panels this how the process works. The radiant energy would come from the sun and get absorbed by the solar panels. In the panels contains Photovoltaics cells which converts the energy from the sun into electric energy. This happens because the cells uses the photons of the sunlight to excite the electrons into a higher state of energy, which give them the ability to act as charge carriers for an electric current. Radiant energy is not just used for electric generation, it is also used for heating. Aside from electrical generation, radiant energy can also be used for heating. The sun’s light is absorbed into the ground and the skin of animals and when radiant energy is absorbed into an object heat is created. Therefore, radiant energy the reason life can exist on Earth because without

thermodynamics, a heat engine is a device/system that uses heat to do work, i.e. it converts heat or thermal energy to mechanical energy. 1.2 How does a heat engine work and its operating principles? For a heat engine to work, it must operate in cycles. Firstly, heat is added into the system. Let the heat added into the system be represented by [Qh]. After that process, some of the energy that were added into the system will be used to do work e.g the materials expanding or increasing in temperature…

The conservation law states that should be equal to zero, and as this wasn’t observed in any trial, it can be said that the conservation law was ineffective in this system. This is also replicated in the loss of kinetic energy. Kinetic energy is being lost in the form of sound as the collision takes place. However, kinetic energy is a scalar quantity, therefore the difference between…
