If there is a massive object floating in space and I tap the side of it with a relatively small force it will move said object a very small amount.
If I tried the same thing on Earth the object would not move because of gravity. I'm inferring (perhaps erroneously) that this means the object is in fact moving but gravity is repositioning the object faster than I displace it?
If this is correct what would happen if I applied a small force very quickly. Would it be possible to outpace the speed at which gravity is moving the object back into position? Would a 1 Newton tap successively applied at an extremely fast rate equal a greater force?
I know F=MA and that acceleration is the rate of change. Is it there for paradoxical to view a force being applied at a rate as the rate is built into the definition?
What is happening when a force is applied continuously such as when I am holding an object in place. Is a force being applied at a "rate"?
I'm confused by this for some reason and if anyone could better characterize what a force is in relation to time I would appreciate it. I suspect its probably confusing for the same reason elastic collisions such as in Newtons cradle are counter intuitive as they deal with infinite quantities.
