A machine is a tool or device that uses energy to perform a specific task. It can be as simple as a lever or a pulley, or as complex as a computer or a car. Machines help us make work easier and more efficient by transforming energy into useful actions. For example, a washing machine cleans clothes automatically, saving us time and effort. Machines come in various forms and serve many purposes in our daily lives. They can be found in homes, factories, and even in nature. For instance, a robot is a type of machine designed to carry out tasks, often mimicking human actions. Overall, machines play a crucial role in modern society, enhancing productivity and convenience.
