The steady speed at which an object free falls is known as the terminal velocity. As an object falls, its speed increases up to a point where the gravitational pull and drag force are equal. At this point, the velocity of the object becomes the terminal velocity, and the acceleration becomes zero.

Webspeed, rate, velocity, pace. 这些名词均含"速度，速率"之意。 speed ： 普通用词，指单位时间内行进的固定速度或速率，也指可能达到的最高速度。; rate作"速度"讲时，与speed同义，可换用。作速率解时，指相对增长的速度，也指两种相比较而得出的标准速度。 WebThe velocity starts at 0 m/s, and then continues to increase as long as the object is falling. So, yes, the object does start slower and will eventually reach speeds faster than 9.8 m/s, but that is velocity and not acceleration. The acceleration remains constant, and is reflecting the increasing velocity of the object as it continues to fall.
