    Why is gravitational acceleration regarded as a constant?

    I am greatly impressed by the knowledge and understanding of the members of these forums. Facebook is a good place to study people in the grip of irrational beliefs, twoofers being particularly grotesque examples. Extracting an infected molar from an unanesthetized Siberian tiger with one's...

    Why is gravitational acceleration regarded as a constant?

    Doc Al, I was asked by my opponent, a 9/11 "truther," to state the point of greatest acceleration when a ball is tossed up in the air. I replied that the acceleration is a constant. He has been ridiculing me ever since without managing to express his precise position in a few coherent sentences.

    Why is gravitational acceleration regarded as a constant?

    In your experience, has a physics text ever asked such a question concerning acceleration and expected an answer that took air resistance into consideration?

    A.T., I confess that your chart is not clear to me. Could you elucidate?

    Why is gravitational acceleration regarded as a constant?

    Many thanks for your prompt response. Yes, I have been doing some reading and the distinction between g and G is becoming clearer. The guy on FB tried to embarrass me by asking me where the acceleration is greatest when a ball is tossed up in the air. I replied that the acceleration is...

    Why is gravitational acceleration regarded as a constant?

    I am hoping to recover some of the knowledge of physics I gained in high school that has vanished into the mists of time. Currently, I am being abused on Facebook by a self-proclaimed authority who ridicules my contention that gravitational acceleration is a constant. I get the idea that gravity...
