Another silly question... Assuming a surface with no friction in space (you get the idea), I push/kick/give a 1kg block on this horizontal plane a force of 1N. It would start to accelerate in the direction i pushed it with at a rate of 1m/s² forever until another force acted upon it. So far so good I hope? Now, is there any difference if I continuously apply 1N in the same direction to it while it travels along its path, would it accelerate any faster? Is "giving" an object a force of 1N in a direction in a single point of time the same as if I were applying 1N to it constantly during the eternity of time? I hope the question is clear enough. Also, could you say that in the first example that the force acting on the object is constant 1N? Or does constant pushing of 1N add the forces together ? (1+1+1...etc?) My hypothesis is that if "kicking" the object in the first example, it would travel at a constant speed, but not accelerate. However in the second example, I think it would accelerate. However I don't know WHY this would be if this is true.. Any good links to read up on this is appreciated, I'm finding the material I read about Newton's laws doesn't cover these types of questions really well, so I end up getting confused all the time.
