Question

An astronaut tosses a ball out in space where gravitational forcesmay be neglected. What will happen to the ball?
It will stop assoon as the force the astronaut gave it is used up.
It will stop whenthe energy the astronaut gave it runs out.
It will stopafter a short time because there is no gravity to keep itmoving.
It will move in acircle like a boomerang.
It will be sloweddown very gradually by collisions with molecules inspace. An astronaut tosses a ball out in space where gravitational forcesmay be neglected. What will happen to the ball?

Explanation / Answer

Newton's law of motion: an object in motion will remain so unlessacted upon by an external force. In space there is no gravityto slow it down so we must rely on friction. So the lastchoice is most reasonable. It will be sloweddown very gradually by collisions with molecules inspace.
