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