If my weight on Earth is a function of F = m x a, where m is my mass, why do I have a weight at all when I am standing on the ground. I understand that the "a" component in the equation for my weight is gravitational acceleration, but my acceleration is zero at that point. If I was in free fall above the earth, I could understand this, but is not my weight while standing on earth equal to my mass times zero acceleration?Please help,Ed
A uniform gravitational field is equivalent to a uniformly accelerating frame of reference.
