Want a study guide too?
Don't let this question about gravitational forces get you down! Yeah, yeah...that was an easy joke. You get what you pay for.

in which direction is the gravitational force directed and hear
the potential answer outward and we're perpendicular All right Well
there's One very large sphere that we should all be
pretty familiar with the earth That big ball All right
Now since we're on planet earth right now let's go
ahead and drop something Nothing expensive by the way Just
pencil Or maybe something soft Now did that pencil go
floating up toward the ceiling Did it start moving sideways
Well so we're probably not actually on planet earth And
in fact we may have been abducted by aliens Well
this has taken a turn and watch for the probing
All right But if we are on earth the things
we drop go downwards towards the core of the planet
So the correct answer is b all the other options
violate the laws of gravity and that's Not gonna happen
The gravity police keep things on lock down The next
time we're playing frisbee with a friend Let's remember to
thank gravity because the game would get really expensive if
the frisbees and never came down You know like a
flying saucer you know e
