Why is there a difference in force required throwing a ball horizontally on the moon and pushing it horizontally it in the spacestation
Thanks
Thanks
The first question would be: What difference are you referring to?Why is there a difference in force required throwing a ball horizontally on the moon and pushing it horizontally it in the spacestation
Thanks
Force doesn't move things, it changes their speed. The relevant equation is Newton's second law ##F=ma##; ##m## is the same in both cases so the same force will change the speed (##a## is the acceleration and that's just another word for "change of speed") by the same amount. And once you've started it moving, in the absence of friction and air resistance it will keep moving, so no matter how small a force you apply for how short of a time if you wait long enough it will have moved one meter.On the space station would it require the same force to move a ball one meter, as it would to move the same ball horizontally one meter on Earth/ the Moon in the absence of friction and air pressure?
Any amount of force in the horizontal direction will "throw the ball horizontally". So this is a misleading statement.Thank you; I will try to be more clear, taking gravity away from all.
On the moon the astronaut requires the same force to throw the ball horizontally in the space station as the astronaut would on Earth.
Any amount of force would start a ball moving in the horizontal direction. How far it will move is just a matter of how long you let it move. So this question can not be answered.On the space station would it require the same force to move a ball one meter, as it would to move the same ball horizontally one meter on Earth/ the Moon in the absence of friction and air pressure?
