I haveve taken into to physics in high school and my teacher was a really great teacher but he was an @ss of a person. In my entire life i have never met someone so mean / ignorant to someone else so i never really asked him anything or tried talking to him so I am trying here. Well here it is. I have seen the little experiment they do to show that no matter how big an object is, if dropped with a smaller / lighter object they will hit the ground at the same time if dropped from the same height. So i think if I'm wrong correct me that they are both falling at 9.8 m/s2. So if gravity is constant how come if i fall from a swing for example and hit the concrete floor i need stitches and if i jump off a building i splatter against the floor? Wouldn't the speed be constant so whats the difference? Thanks a lot i thought of this earlier and just couldn't find anyone with an answer so i thought i would try online.
