Mechanical work refers to the energy transferred by a force that causes an object to move a certain distance. Here's a detailed description:

Mechanical work is a measure of the energy expended in moving an object from one place to another. It is calculated as the product of the force applied and the distance over which the force is applied:

Work = Force x Distance

The unit of mechanical work is typically measured in joules (J), where 1 joule is equal to 1 newton-meter (N·m).

Examples of mechanical work include:

- Lifting an object against gravity
- Pulling or pushing an object horizontally
- Rotating an object using a force applied at a distance from the axis of rotation

Mechanical work is a fundamental concept in physics and engineering, and it has numerous applications in various fields, including mechanics, thermodynamics, and energy production.
