Work and energy are closely related concepts in physics. Work is defined as the transfer of energy that occurs when a force is applied to an object and the object moves in the direction of the force. The amount of work done on an object is equal to the force applied multiplied by the distance the object moves in the direction of the force.
Energy, on the other hand, is the ability to do work. There are several forms of energy, including kinetic energy (energy of motion), potential energy (stored energy), and thermal energy (heat energy). The total energy of a system is conserved, meaning it cannot be created or destroyed, only transferred from one form to another.
In summary, work is the transfer of energy that occurs when a force is applied to an object, and energy is the ability to do work. The relationship between work and energy is fundamental to understanding the behavior of physical systems.

Work
- Definition: The transfer of energy into or out of a system by the application of a force that moves the system through a distance.
- Equation: W = F x d
- W: Work done (in joules)
- F: Force applied (in newtons)
- d: Distance moved (in meters)
- Units: Joule (J)
Energy
- Definition: The capacity to do work.
- Types:
- Kinetic energy (KE): Energy of motion
- Potential energy (PE): Energy due to position or configuration
- Thermal energy: Energy associated with the movement of particles
- Chemical energy: Energy stored in chemical bonds
- Electrical energy: Energy carried by electric charges
- Equation: E = W
- E: Energy (in joules)
- W: Work done (in joules)
Relationship between Work and Energy
- Work is the process by which energy is transferred.
- When work is done on a system, its energy increases.
- When work is done by a system, its energy decreases.
Other Key Concepts
- Conservation of energy: Energy cannot be created or destroyed, only transferred or transformed.
- Power: The rate at which work is done or energy is transferred.
- Equation: P = W / t
- P: Power (in watts)
- W: Work done (in joules)
- t: Time (in seconds)
- Efficiency: The ratio of useful work output to the total energy input.
- Equation: Efficiency = Wout / Win
- Wout: Useful work output (in joules)
- Win: Total energy input (in joules)
