Thank you We sneak and here's your smoke du jour

Brought to you by space Travelling hats Yeah cats already

will mrs north has inertial and gravitational mass on the
- 00:26
moon compared to her inertial and gravitational mass here on
- 00:30
earth and here the potential answers All right way less
- 00:34
rude That okay got him All right Well let's take
- 00:39
a moment and let that mass in our skulls Think
- 00:42
about what exactly mass is Well people often confuse mast
- 00:47
and wait Mass is a measure of how much matter
- 00:50
an object has Weight is a measure of gravity's force
- 00:54
acting on that mask So wait changes as gravity changes
- 00:59
For example some of the ways one hundred twenty pounds
- 01:00
on earth would weigh about twenty pounds on the moon
- 01:04
But mass doesn't depend on gravity After all if all
- 01:07
of sudden were launched into space there just a cz
- 01:10
much of us up there as there was on earth
- 01:13
It's just that in space we don't experience the force
- 01:16
Of gravity and mass But it plainly is just mass
- 01:20
It could be measured in terms of gravitational mass or
- 01:22
inertial mass but those are really just different ways of
- 01:25
measuring the same mass well Something that has fifty kilograms
- 01:29
of inertial mass will also have fifty kilograms of gravitational
- 01:33
mass option A treats mass and weight is the same
- 01:36
thing and we know that's wrong being searing correct to
- 01:39
since gravitational mass and inertial mass are equal Just because
- 01:42
we reduced gravity doesn't mean a gravitational mass changes All
- 01:46
of this has been leading to the correct answer option
- 01:49
d the mass of something or some cats doesn't change
- 01:54
whether it's on the moon or on earth But the
- 01:56
answer is d
