If you drop a bowling ball and a tennis ball from the same height, which hits the ground first? The idea of the question is you’d assume the heavier object would fall faster, but as I was taught as a kid, they both hit at the same time. But now I’m thinking that doesn’t make any sense.
If I remember correctly, the two main variables affecting gravity are mass and distance. Since we’re holding distance constant with the bowling ball and the tennis ball, that means I’m supposed to believe that two objects with different masses have the same acceleration? Well, what would hit first: A bowling ball dropped from one meter on Earth or a bowling ball dropped from one meter on Mars? The bowling ball on earth obviously, as the increased mass of Earth versus Mars results in increased acceleration. Because mass matters.
It seems to me the fallacy of saying the bowling ball and the tennis ball fall at the same speed is thinking the mass of the Earth is so great compared to the two balls that you can discount their mass. But, scientifically, that can’t be true. The bowling ball being more massive is going to pull back on the earth more than the tennis ball and thus accelerate faster (or would the tug slow it down in any way?). It won’t be discernible to the human eye, but the bowling ball’s fall at least won’t be gravitationally the same as the tennis ball’s.
So, to whomever taught me objects all fall towards earth at the same rate regardless of mass, I am now formally calling shenanigans. That’s either wrong or requires much more of an explanation.
