An accelerometer is an instrument that measures acceleration rather than velocity, finding applications in a wide array of fields including seismic monitoring, mobile devices, and aerospace engineering.
Jet propulsion is a method of propulsion that generates thrust by expelling fluid, commonly used in jet engines and rockets. Unlike propellers which generate thrust through rotating blades, jet propulsion achieves forward momentum by ejecting high-speed exhaust.
A Rocket Scientist, often representing high intelligence and expertise in aerospace engineering, can develop new techniques or products. The term can be used negatively to imply that a subject is easily understandable. See also No-Brainer and Quant.
