| 00:11 | so get this . I saw a commercial for one | |
| 00:14 | of those crazy weight loss plans on tv this morning | |
| 00:17 | . What kind of wacko fad diet is it this | |
| 00:19 | time ? It's got to be better than that . | |
| 00:21 | All salt one . We saw actually this promise you | |
| 00:25 | can eat whatever food you wanted and still lose weight | |
| 00:28 | . Sounds sketchy and you don't have to exercise either | |
| 00:31 | . Sounds really sketchy . What's the catch ? There | |
| 00:33 | isn't any . Okay . You have to go to | |
| 00:36 | the moon . Really ? Let's check this out totally | |
| 00:40 | . At least we'll get to visit the moon . | |
| 00:43 | Hi . We're interested in your extraterrestrial weight loss program | |
| 00:47 | . Yes of course . We'll start by taking a | |
| 00:49 | baseline measurement . How much do you weigh now miss | |
| 00:53 | ? You know what ? Why don't we have the | |
| 00:55 | gentleman way himself ? Much better . The scale weighs | |
| 00:59 | 100 g duly noted . Now for step to lift | |
| 01:03 | off . So this is the moon . Huh ? | |
| 01:06 | How about that sir ? If you'll just step up | |
| 01:09 | for another weighing It's a 16.6 g . Well there | |
| 01:13 | you have it . Look at all that weight you've | |
| 01:14 | lost . That will be $5 million . Please . | |
| 01:17 | We take checks . And actually your scales wrong . | |
| 01:20 | What ? It's calibrated for Earth and it's showing his | |
| 01:23 | mass incorrectly . I don't understand what you're talking about | |
| 01:27 | . We can explain there are two different quantities that | |
| 01:30 | can be confused . Mass and weight . Mass is | |
| 01:33 | the measure of how much matter and objects like my | |
| 01:35 | body contains . On the other hand , weight is | |
| 01:39 | a force measures how much a planet is pulling down | |
| 01:42 | on an object . Weight is measured in units of | |
| 01:45 | Newton's or pounds . Force . Mass is measured in | |
| 01:48 | units of kilograms or pounds . Mass . Or slugs | |
| 01:54 | . It's funny because we're slugs . I thought you | |
| 01:58 | were just homeless snails . Yeah , we're not . | |
| 02:02 | Mass and weight are related . But there's a big | |
| 02:04 | difference between the two how they are affected by the | |
| 02:07 | gravity of a planet . John's mass isn't different from | |
| 02:10 | what it was on earth . He hasn't lost or | |
| 02:12 | gained any matter . And so he's 100 g here | |
| 02:15 | , there and everywhere . Although I almost threw up | |
| 02:18 | in the rocket on the way here , I'm glad | |
| 02:20 | you didn't . I had a guy last week throw | |
| 02:22 | up . It cost me $1,000 to clean . You | |
| 02:24 | should really get some of those little paper bags for | |
| 02:26 | people . Sorry . As I was saying , john's | |
| 02:32 | mass hasn't changed , but his weight has its smaller | |
| 02:36 | here on the moon than it was on Earth . | |
| 02:39 | And that's because the gravity here on the moon is | |
| 02:41 | smaller than the gravity on Earth . Six times smaller | |
| 02:44 | to be exact . Which means my weight is six | |
| 02:47 | times smaller too . I weighed .98 Newtons on Earth | |
| 02:51 | . But I only way .16 newtons here on the | |
| 02:54 | moon . Well , what if we went around to | |
| 02:56 | other planets ? Like in this convenient rocket ship I | |
| 02:59 | happen to have right here ? Well , on some | |
| 03:02 | planets , jOHN weighs less than needed on earth . | |
| 03:05 | Mercury , venus , but just barely mars uranus and | |
| 03:15 | Pluto Pluto . I thought you said planets . Well | |
| 03:19 | , it's a dwarf planet . Does that count ? | |
| 03:21 | I guess on other planets , johN weighs more than | |
| 03:25 | he did on earth . Like Neptune , Saturn and | |
| 03:30 | jupiter . And if we had to the sun , | |
| 03:33 | we are a lot heavier . You guys smell something | |
| 03:37 | burning . It's like an s car , go smell | |
| 03:42 | . Uh , we should head back . Okay . | |
| 03:46 | So I understand the difference between mass and weight . | |
| 03:48 | But now I'm all confused about my scale . We | |
| 03:51 | measure our weight on the scale , but it gives | |
| 03:53 | the answer on kilograms , which is the unit of | |
| 03:54 | mass . What's the scale ? Really measuring the scale | |
| 03:58 | measures your weight , but it displays mass . It's | |
| 04:01 | able to make the conversion because it's calibrated to include | |
| 04:03 | the gravity of Earth . But whenever you're here on | |
| 04:06 | the moon , the scale displays the wrong mess to | |
| 04:10 | self by new scale . But hey , I promise | |
| 04:14 | to weight loss and you've got a weight loss $5 | |
| 04:17 | million , please . True . But what people really | |
| 04:22 | want is a mass loss program . We often use | |
| 04:25 | the words interchangeably on Earth because the gravity is not | |
| 04:28 | changing . Yeah , I want to get rid of | |
| 04:30 | some of my mass right here on my stomach area | |
| 04:33 | or rather molly wants me to get rid of it | |
| 04:36 | . I just think you could eat a little less | |
| 04:38 | ice cream and go for a walk every now and | |
| 04:40 | then . |
