By Newton's first law, if there is no net force on an object, then its velocity is not changing.

anonymous · Answer

So the answer is B?

anonymous · Answer

No.  It could be moving, but it would be staying at the same velocity.  Non-changing velocity does not imply stationary.

anonymous · Answer

Oh am confuse...whats the answer?

anonymous · Answer

D or possibly C.  The fact that there is no net force on the box tells you only that it is not accelerating.  It might be motionless, or it might be moving at a steady velocity.  C is possible because the box is always "affected" by gravity, because everything is.  But "affected" isn't a precisely defined physics term, so I don't really know what the choice means.  If it means the box is under acceleration due to gravity, then it is not true.  If it means one of the forces on the box is in principle gravity, whether or not there is a large body nearby to exert it -- there is always SOME gravity around, even if it is a profoundly weak force from distant stars -- then it is true.

C doesn't really answer the question, to be honest...it's like answering "banana".  I'd go with D.

Thanks very much even tho i answered it and got it wrong already...i will know next time
