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:
Aaaaaand we have liftoff! On another shmoopy question, that is. Take a look at this question and see if you can figure it out. Don't worry if you can, just say "Shoomp-ston, we have a problem" and we'll help you out.

following is true about the situation Select two answers your
- 00:23
tens ones All right Well there are two important things
- 00:27
we need to remember in order to answer the question
- 00:29
The first is that if something has mass than it
- 00:31
has gravity it doesn't matter if that something is as
- 00:34
big as a star or a small is a pebble
- 00:37
We also need to remember the gravity doesn't go away
- 00:41
now the father away from an object we are the
- 00:43
less we feel the force of that gravity But that
- 00:46
doesn't mean the gravity has stopped After all we know
- 00:49
about the gravitational constant right Well with this knowledge in
- 00:52
our back pocket we can rule out option a or
- 00:55
a still exerts a gravitational pull on the spaceship All
- 00:58
right option d is incorrect to the spaceship doesn't begin
- 01:01
to generate its own gravity It's always generated its own
- 01:05
Gravity but the further away we get from the object
- 01:08
well yeah then the less gravitational force that object exerts
- 01:12
on this For example gravity on jupiter is two and
- 01:15
a half times stronger than gravity on earth but because
- 01:18
we're so far away from jupiter will never feel that
- 01:21
pull All right so option c is one of the
- 01:25
correct answers The gravitational force exerted by the earth decreases
- 01:28
as the spaceship travels further away Yeah and we're left
- 01:32
with option b is our other correct answer Wait is
- 01:35
dependent on gravity that's why things float in space where
- 01:38
gravity is weak but mass is mass It doesn't change
- 01:43
masses what an object is made of whether we're talking
- 01:46
about inertial mass or gravitational mass Gravitational mass refers to
- 01:50
a method of measuring mass but it doesn't change depending
- 01:52
on gravity So there we have it Our answers here 00:01:55.08 --> [endTime] a b and c
