in which direction is the gravitational force directed and hear

00:20

the potential answer outward and we're perpendicular All right Well

00:25

there's One very large sphere that we should all be

00:28

pretty familiar with the earth That big ball All right

00:32

Now since we're on planet earth right now let's go

00:34

ahead and drop something Nothing expensive by the way Just

00:37

pencil Or maybe something soft Now did that pencil go

00:40

floating up toward the ceiling Did it start moving sideways

00:43

Well so we're probably not actually on planet earth And

00:45

in fact we may have been abducted by aliens Well

00:48

this has taken a turn and watch for the probing

00:51

All right But if we are on earth the things

00:53

we drop go downwards towards the core of the planet

00:56

So the correct answer is b all the other options

00:59

violate the laws of gravity and that's Not gonna happen

01:02

The gravity police keep things on lock down The next

01:04

time we're playing frisbee with a friend Let's remember to

01:06

thank gravity because the game would get really expensive if

01:09

the frisbees and never came down You know like a

01:12

flying saucer you know e
