the law of universal gravitation
true
False.
Of course false
False: The entire universe (including Earth) has gravity, weak force, strong force, and electromagnetic force.
True. A body of mass M will have zero weight in outer space.
No, that is false. "Free fall" means that the only force acting on an object is GRAVITY. Specifically, there may be no significant amount of air resistance. It's not quite possible for the only force acting on an object to be air resistance, since you can't really eliminate the effect of gravity. Though, if the object has the same density than the liquid or gas in which it is placed, the gravity may be cancelled for practical purposes.
False.

AnswerSome say God; some say a false vacuum.
False
False. (Electromagnetic forces stop the motion.)
False: The entire universe (including Earth) has gravity, weak force, strong force, and electromagnetic force.
True. A body of mass M will have zero weight in outer space.
i think its true

That is true! Weight is how much gravity is pulling on an object. For example, on the moon, an object will weigh about 6 times less than it does on Earth. Mass, on the other hand, stays the same ALL THE TIME, no matter where you are.
