What has more inertia: a full water bottle sitting on a desk, or a football player running with the ball?

According to the First Law of Motion or Law of Inertia, Inertia is the tendency for an object to resist change in its velocity. If you look at your scenario you have a full water bottle on a desk and a football player running with the ball. The water bottle is at REST  because is not moving while the football player is IN MOTION, because he is running.

Now the question is would it be easier to make the water bottle move or to make the football player stop?  

It is easier to make the bottle move than stop the football player. Since the running football player shows more resistance to a change in its motion, then it has more inertia. 

Julia would be observing a. static electricity was caused by her sweater rubbing against her shirt and transferring electrons. she didn't touch anything metal, so that would cancel out b.she most likely didn't rub her sweater against her hair either, so that cancels out c.she also didn't scoot across the carpet while trying to take her sweater off, that cancels out d.so that leaves a.a. is correct.
