Pneumatic tool Pneumatic tool A pneumatic tool, air tool, air-powered tool or pneumatic-powered tool is a type of power tool, driven by compressed air, supplied by an air compressor. Pneumatic tools can also be driven by compressed carbon dioxide () stored in small cylinders allowing for portability. Most pneumatic tools convert the compressed air to work using a pneumatic motor. Compared to their electric power tool equivalents, they are safer to run and maintain, without risk of sparks, short-circuiting or electrocution, and have a higher power to weight ratio, allowing a smaller, lighter tool to accomplish the same task. Furthermore, they are
Binding energy Binding energy Binding energy (also called separation energy) is the "minimum" energy required to disassemble a system of particles into separate parts. This energy is equal to the mass defect - the amount of energy, or mass, that is released when a bound system (which typically has a lower potential energy than the sum of its constituent parts) is created, and is what keeps the system together. If the energy supplied is more than the binding energy, then the disassembled constituents possess non-zero kinetic energy. In general, binding energy represents the mechanical work that must be done against the forces
