okay, so i have two questions. the first one is, since there is no terminal velocity in a vacuum (this is true, right?), would an object continue to accelerate indefinitely? or is there some other force that would stop the acceleration at some point?
also, since symmetry dictates that a body that travels upwards through space must take the same amount of time to travel downwards through space (this is also true i think?), then if a bullet were shot straight up in the air, would it be just as deadly on the way back down as on the way up?
my husband and i launched into a huge debate over these simple physics laws, and since our combined distance from high school physics is almost 20 years, we figured we should probably consult someone who knows what they are talking about
