What is the term for acceleration that occurs during takeoff and landing?

The term for the type of acceleration that occurs during takeoff and landing is linear acceleration. This form of acceleration is characterized by a change in velocity as an object moves in a straight line. During takeoff, as the aircraft accelerates down the runway, it increases in speed until it reaches a velocity that allows it to lift off the ground. Similarly, during landing, the aircraft must decelerate as it approaches the runway, resulting in a change in speed in a straight trajectory until it comes to a stop.

Linear acceleration is distinct from other types of acceleration such as radial, angular, and centripetal acceleration. Radial acceleration refers to the change in direction experienced by an object moving along a curved path, while angular acceleration pertains to the rate of change of angular velocity, relevant in rotational movements. Centripetal acceleration is the acceleration that keeps an object moving in a circular path and is directed towards the center of that path. Understanding linear acceleration is crucial for pilots and those studying aerospace physiology, as it directly relates to the forces experienced during critical phases of flight.
