Pneumatic systems work, because they are pumped through the pipes and tubes with a enormous force. As they are travelling, they lose speed, but more pumps speed them up. The gas soon gets to its destination. Hopes this helps!!!

Pneumatic systems use compressed air to transmit energy. When air is compressed in a storage tank or reservoir, it can be directed through pipes or hoses to drive cylinders, motors, or other actuators. This compressed air creates force that can be used to power various mechanical processes in machinery and equipment.
The standard unit used to measure shaft work in mechanical systems is the Joule (J).
The work sign convention is a set of rules used to determine the direction of work done by forces in mechanical systems. It impacts the analysis of mechanical systems by helping to accurately calculate the energy transfers and determine the overall behavior of the system.
The work-energy relationship states that the work done on an object is equal to the change in its kinetic energy. This means that when work is done on an object, it gains or loses energy in the form of kinetic energy. This relationship helps explain how energy is transferred within physical systems, as work done on an object can change its energy state.
In thermodynamics, the concept of work is the energy transferred when a force acts on a system to cause a displacement. This work is a key factor in understanding the behavior of systems in thermodynamics, as it helps determine how energy is transferred and transformed within the system. The amount of work done on or by a system can affect its internal energy, temperature, and overall behavior.
Pulley systems do not change the amount of work done; they only change the direction or magnitude of the force applied. In an ideal pulley system, the work input is equal to the work output, neglecting friction and other losses. The mechanical advantage gained from a pulley system allows the same amount of work to be done with less force or over a shorter distance.
