We've heard of some crazy dieting fads, but leaving the planet may take the cake. We don't suggest you do that, but we do suggest you answer t...
Don't let this question about gravitational forces get you down! Yeah, yeah...that was an easy joke. You get what you pay for.
THE EARTH'S MASS IS ABOUT TO DOUBLE. Sorry for the extreme tone; we just want to make sure you understand the...gravity of the situation.

Description:
There's a giant blob monster attacking New York. Luckily, Shmoop isn't based in New York, so you don't need to worry about getting your fill of shmoopy test prep questions. Students in New York on the other hand, well....they've got bigger blobs to fry.

Thank you We sneak and here's your shmoop du jour
- 00:05
brought to you by blob monsters We've never seen one
- 00:08
but they probably looks something like we do after thanksgiving
- 00:11
dinner All right A giant blob monster is attacking new
- 00:15
york and suddenly doubles in mass if the original force

of gravitation exerted upon it is expressed as f which
- 00:23
of the following represents the new gravitational force after its
- 00:28
change in mass and here the pendulums happened All right
- 00:33
so we've got a block attacking new york The blob
- 00:35
actually isn't a very scary monster It's really Just a
- 00:38
big slow moving bunch of goo To answer this question
- 00:41
we need to know how to calculate the gravitational force
- 00:44
acting on an object and to find that force we
- 00:47
take the objects mass and multiply it by gravity like
- 00:51
f equals mg like that Now if we were in
- 00:53
a double mass the equation would now be force equals
- 00:58
two times mass times gravity or two mg which means
- 01:02
that the force exerted would be double no The correct
- 01:05
answer here is c to f but let's not devalue
- 01:09
Blob monsters Too much after all a monster self worth
- 01:12
Is often based on how scary it is And we 00:01:14.89 --> [endTime] wouldn't want to hurt its feelings
