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
Electric potential energy Electric potential energy Electric potential energy, or electrostatic potential energy, is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system. An "object" may have electric potential energy by virtue of two key elements: its own electric charge and its relative position to other electrically charged "objects". The term "electric potential energy" is used to describe the potential energy in systems with time-variant electric fields, while the term "electrostatic potential energy" is used to describe the potential energy in systems with
