Work equals the change in energy, in a closed system energy is not lost. So in a closed system any work done will be countered by an equal and opposite work. An example is throwing a ball up into the air and catching it again. The work done by you to accelerate it is equal and opposite to the work done by the earth.

How is work related to mechanical energy?
Work is related to mechanical energy because when work is done on an object, it can change the object's mechanical energy. Mechanical energy is the sum of an object's kinetic energy (energy of motion) and potential energy (stored energy). When work is done on an object, it can increase or decrease the object's kinetic or potential energy, thus affecting its overall mechanical energy.
What was James Joule famous for?
James Joule was famous for his work in the field of thermodynamics, particularly for discovering the relationship between mechanical work and heat energy. This led to the development of the first law of thermodynamics, also known as the conservation of energy principle. Joule's experiments helped establish the concept of the mechanical equivalent of heat.
what is the role of Joule's experiment in establishing the principle of conservation of energy?
total energy IS CONSERVED and the principle of conservation of energy does hold
Who gave the relationship between mechanical energy and heat energy?
The relationship between mechanical energy and heat energy was established by James Prescott Joule through his experiments in the mid-19th century. Joule's work demonstrated the principle of conservation of energy and showed that mechanical work could be converted into heat energy.
What is James joule famous for?
James Joule is famous for his work in the field of physics, particularly for establishing the relationship between heat and mechanical work. He formulated the law of conservation of energy and the first law of thermodynamics, which are fundamental principles in our understanding of energy. Joule also developed the concept of the mechanical equivalent of heat, which quantitatively relates mechanical work to heat energy.

How are potential and kinetic energy related to mechanical energy?
they both do work

What is the difference between conservation of mechanical energy and conservation of total energy?
Conservation of mechanical energy states that the sum of kinetic and potential energy remains constant in a system with only conservative forces at work. On the other hand, conservation of total energy includes all forms of energy including mechanical, thermal, chemical, etc. and states that the total energy of a system remains constant in the absence of external forces like friction or air resistance.

Is energy the same thing as work?
Not exactly, but they are closely related. Both have the same units, but "work" specifically refers to a TRANSFER of mechanical energy. When "work is done", mechanical energy is transferred from one object to another.
How is flow energy related to thermodynamics?
Flow energy is related to thermodynamics through the concept of energy conversion and conservation. In thermodynamics, flow energy refers to the energy associated with the movement of fluids or gases. This energy can be converted into other forms of energy, such as mechanical work or heat, according to the laws of thermodynamics. The conservation of energy principle in thermodynamics states that energy cannot be created or destroyed, only transferred or converted from one form to another. Therefore, understanding flow energy is crucial in analyzing and predicting the behavior of systems in thermodynamics.
How work and enery related?
I am not sure whether it is the official definition, but I like to think of work as a transfer of mechanical energy.
How is mechanical energy transferred in various systems and processes?
Mechanical energy is transferred in various systems and processes through the conversion of potential energy into kinetic energy. This transfer can occur through mechanisms such as friction, collisions, and work done by external forces. The conservation of mechanical energy principle states that the total mechanical energy in a closed system remains constant, with potential energy transforming into kinetic energy and vice versa.
Is mechanical energy always conserved why or why not?
Mechanical energy is not always conserved. It can be converted into other forms of energy such as heat, sound, or work, due to external forces like friction or air resistance acting on the system. In the absence of non-conservative forces, mechanical energy is conserved according to the law of conservation of energy.
