Work is the ability to move kinetic energy in different directions. Energy on the other hand can be used for rest and for work.
Contrast radiant energy and sound energy are both forms of energy that can travel through a medium, such as air or water. Contrast radiant energy travels as electromagnetic waves, while sound energy travels as mechanical waves. Both forms of energy can transfer from one object to another.
Negative work occurs when the force applied to an object is in the opposite direction of the object's motion, resulting in a decrease in the object's energy. In contrast, positive work occurs when the force applied is in the same direction as the object's motion, leading to an increase in the object's energy.
work done by fuel is conversion of chemical energy into mechanical whereas work done by moving object is due to its displacement by the application of force. actually, both of them give same meaning.
The conversion of chemical energy to kinetic energy is typically the most efficient, with efficiencies in the range of 20-40% in combustion engines. In contrast, the conversion of thermal energy to mechanical work in heat engines is generally less efficient, with efficiencies typically below 30%.
Basically, work refers to an energy transfer.
Energy is the ability to do work or cause change.
In a sense, work can be seen as the transfer of energy between a system and its surroundings. When work is done on a system, energy is transferred to it, and when work is done by a system, energy is transferred to its surroundings. This transfer of energy through work is a fundamental concept in physics.
Energy is the ability to do work, and work is the transfer of energy from one object to another by applying a force over a distance. In other words, energy is a property of a system that allows it to do work, while work is the process of transferring that energy between systems.
The forms of energy that do work is kinetic energy.
chemical energy is when the energy that is released when a chemical compound reacts to produce new compounds. A mechanical energy is the sum of the kinetic and potential energy of large-scale objects in a system.
Thermal energy is the sum of the kinetic energy and the potential energy of the particles in a material. Heat is a form of energy transferred by differences in temperature. These are both forms of energy.
Work and energy are related in the sense that work is the process of transferring energy from one system to another. When work is done on an object, energy is transferred to that object, either increasing its kinetic energy (if the work is done against friction) or potential energy. The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy.
