A rocket engine is a propulsion system that generates thrust by expelling mass at high velocity, typically through the combustion of propellants. It operates on Newton's third law of motion, where the reaction force from the expelled gases propels the rocket in the opposite direction. Rocket engines can be classified into two main types: liquid engines, which use liquid propellants, and solid engines, which use solid propellant compositions. These engines are essential for launching spacecraft and carrying payloads beyond Earth's atmosphere.

A digital tachometer measures the rotational speed of an object, typically in revolutions per minute (RPM). It works by using sensors, such as optical or magnetic pickups, to detect the rotation of a shaft or wheel. This data is then processed by an onboard microcontroller, which calculates the RPM and displays the result on a digital screen. Unlike analog tachometers, digital models provide more precise readings and can often include additional features like data logging or integration with other electronic systems.
