Pneumatics is the term that specifically refers to the use of compressed air to create mechanical motion. In pneumatic systems, compressed air is utilized to transmit and control energy, which can then produce movement in various applications such as automated machinery, tools, and actuators.

Understanding the principles of pneumatics is crucial because this technology is widely used in industrial settings for processes requiring speed and simplicity. Systems using compressed air are often preferred due to their cleaner operation compared to alternatives that rely on liquids or chemicals, as well as their ability to operate in various environments without concerns about leaks or contamination.

The other terms, while related to motion and energy transfer, do not apply to the specific context of air-based systems. Hydraulics, for example, involves fluids under pressure (usually liquids) to transmit force, while electromagnetism relates to electromagnetic forces rather than fluid dynamics. Mechanical leverage pertains to the use of levers and physical force rather than fluid systems.
