acceleratore

Acceleratore is the Italian term for accelerator, used to describe devices or systems that increase speed. The word derives from Latin accelerare, meaning to hasten, and is widely used in Italian to refer to both mechanical components and metaphorical concepts. In everyday language, acceleratore commonly denotes the pedal in a vehicle that controls engine throttle, but the term also appears in scientific and business contexts.

In automotive use, the acceleratore is the accelerator pedal. Pressing it modulates the engine's power input, either through a mechanical linkage or, in modern cars, an electronic throttle control system that adjusts fuel delivery and air intake remotely. The pedal's position is usually sensed by a sensor and translated into engine commands by the vehicle's control unit.

In physics, an acceleratore di particelle (particle accelerator) is a device that increases the kinetic energy of charged particles. Machines come in linear and circular forms; RF cavities provide accelerating fields and magnets steer and focus the beam. Particle accelerators enable fundamental research, materials science, and medical applications such as radiation therapy.

In business and technology, an acceleratore or startup acceleratore is a program designed to accelerate the growth of young companies. Such programs offer mentorship, training, workspace, and often seed funding, typically over a period of several weeks to months, with a culminating demo day or evaluation.

Other specialized uses exist, but across contexts the core idea remains: to increase speed, momentum, or progress through a defined mechanism or program.
