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

00:05

Brought to you by space Travelling hats Yeah cats already

00:10

rule the internet so outer space seems like the logical

00:12

next step right Right Mr filch builds a teleporter and

00:17

sends his pet cast this's norris to the moon How

00:22

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
