It's not speed, it's the height over time. The derivative of this is the speed, and then the axis in this case should not start at 0, it should start at negative because there are periods where the speed is negative.

    It’s not speed, it’s the height over time

    yeah, it is not speed, it is unit over time, so, wait for it... speed.

    The derivative of this is the speed

    and its visual perception is distorted due to the truncated axis.

    it should start at negative because there are periods where the speed is negative.

    "where the speed is negative"? wait, what, i thought this is not speed - as per your first sentence. also, the axis should start at zero, because... at some point the height of the person was negative?

    well thank you for your input 😂

    Height as a function of time results in... Height. Delta height divided by Delta time is average speed. This is basic math.

    If this was speed, there would be points of negative speed, when height is lower at a greater time.

    I'm going to assume you're just a troll, nobody can be so dumb.

    Edit: just as an observation, if you want to look at the speed, the truncated axis is irrelevant, because the intersection value is derived to 0. You really don't know this?

    there is no need for the height axis to start below zero just because there is negative speed at some point. i am going to assume you are just dumb, because i do believe people can be that dumb.
