    I haven’t seen anyone mention this yet, so here’s how I understand it. The feather falls slower in non-vacuum conditions because it reaches its terminal velocity much more quickly than the bowling ball.

    Edit: terminal velocity: https://en.m.wikipedia.org/wiki/Terminal_velocity

    Also edit: https://ucscphysicsdemo.sites.ucsc.edu/physics-5a6a/coin-and-feather/#:~:text=Because the feather has a,small%2C the feather falls slowly.

      How would it reach terminal velocity in a vacuum?

        I imagine terminal velocity with no air resistance would be 9.8m/s/s. I was saying that the feather reaches terminal velocity more quickly than a bowling ball in non-vacuum conditions

          9.8 m/s/s is acceleration due to gravity, not a velocity, or its units would be m/s

          The terminal velocity in a vacuum is like the speed of light.

          Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example). It is reached when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has zero acceleration

          Objects in a vacuum have no drag and no terminal velocity…
