What Do You Know About Flight Dynamics?
In the science of flight, flight dynamics is a useful concept, along with a set of principles, widely used in aircraft, spacecraft, and satellites. This concept uses the understanding of three quantities (force, speed, and time) to help scientists understand vehicles flying in outer space or through the air and their control, stability, and performance.
