because it involves only an abstract idea, not a material object.
If an object is above ground level, it has positive gravitational potential energy. (This assumes you define ground level to be zero - actually, you can define any level to be zero.)
In fact : no one. Some people do use cleaner energy than others, but that just means that you must define your terms.
Energy that has been used from ancient times is known as conventional energy. Coal, natural gas, oil, and firewood are examples of conventional energy sources.Basically A Fossil Fuel.
Isothermal expansion is what keeps gas at a constant temperature. It works by absorbing heat in order to conserve energy.
Fossil fuels are significant for scientists because they are a primary source of energy that has powered industrial development and economic growth for over a century. They contain stored solar energy from ancient organic matter, and their combustion releases carbon dioxide, a key factor in climate change. Understanding fossil fuels is crucial for addressing environmental impacts and developing sustainable energy alternatives. Additionally, studying their formation and depletion can provide insights into geological processes and Earth's history.
they define when work occurs energy. Energy is the ability to do work.
Scientists define energy as the ability to do work or cause a change. It can exist in various forms such as kinetic, potential, thermal, or electromagnetic energy. Energy cannot be created or destroyed, but only transformed from one form to another.
Energy is hard to define because it comes in various forms and can be transferred or transformed in many ways. Additionally, energy is a concept that is used to describe the capacity of a system to do work or produce heat, making it abstract and difficult to pin down with a single, universally agreed upon definition.

The definition of energy is the ability to work.
Why is energy difficult to measure?
Scientist define energy as the ability to do work or to cause change. It is a scalar quantity that can be transferred between objects or converted into different forms. Energy exists in various forms such as kinetic, potential, thermal, chemical, nuclear, and electromagnetic.
Light energy has been observed and studied by humans since ancient times. The Ancient Greek philosopher Empedocles was one of the earliest to propose that light travels in straight lines. The concept of light energy has evolved over centuries through the work of scientists such as Isaac Newton and Albert Einstein.

Earthquakes are difficult to predict because they are caused by the sudden release of energy in the Earth's crust, which is complex and constantly changing. Scientists have not yet found a reliable way to accurately forecast when and where earthquakes will occur.
