Lose Weight? Lose Mass!

[coka011]

Holla! Have you tried intellectus 424 diet (do a search on google)? Ive heard some unbelivable things about it and my buddy lost crazy amounts of weight with it.

An objects weight is the product of its mass and the local gravitational field.

They were incorrect by using the term "force of gravity"...weight IS the force of gravity.

danno1111 is correct, but gravitational field strength is not necessarily equal to a body's acceleration. Only when no other forces act on a body is its acceleration equal to the local gravitational field strength.

@Gintable and @danno1111 you are both correct, I bleeped up by calling it "force of gravity". It is, indeed, the acceleration due to gravity. My intention, though, was to say that the force of gravity affects your weight (the force), I just didn't explain myself as accurately as you point out I should have. I hope the general intent is clear, though, and thanks for the comments!

[danno1111]

An objects weight is the product of its mass and the *acceleration* due to gravity, not the "force" of gravity...

Also, strictly speaking, the astronaut in orbit around the earth isn't weightless, since the force due to gravity is still acting on his body (albeit, at some fraction of what it is on the Earth's surface).

Cool Video. I've gotten lean over the past year from weigh lifting. I've stayed the same mass, I just take up less space because I am denser!

[smarterthanthat]

Yay, good for you, ayk1987, You've gotten leaner *and* scienc'ier! ;)

[ajgrovery]

wouldnt brag about being denser lol

[ayk1987]

Why not? Muscle is more dense than fat? I lost fat and gained muscle.

[ajgrovery]

think about it

what else could denser mean?

[ayk1987]

Funny

[ajgrovery]

thanks :D

[CuMeiLin]

your channel is really amazing!!! ILOVESCIENCE!!!

[riedsa]

Moo... Can I use this?

[mooeypoo]

Yes! My site's creative commons -- just link back to picture source (or the smarterthanthat page that has them).

[Brianswers]

informative vid, thanks! I want to lose weight. When is the next shuttle to the space station? :)

[SuperFinGuy]

Wow welcome back!

[TomSFox]

Where have you been, little miss?

[farvision]

Units units units! Weight = mass x force of gravity? Shouldn't the units be 'force of gravity per mass"?

Then weight would be a pure force.

Odd synchronicity that you uploaded a new video after so long, within hours of me doing the same, having lost a lot of my weight (sorry, MASS!) through exercise. Great video. More please - we missed you!

[BorgHub]

welcome back moo!

[CousinoMacul]

"The particles that make you you didn't go anywhere."

Yes they did: they went to the Moon! ;-)

Great to see you back. Make MOAR videos puhleeze! :-)

[sheepwshotguns]

hey hey, she's back! =D

[JeanMichelAbrassart]

Nice vid'. :)

[AtSwimTwoBricks]

You're back! And covering very topical topic--I'm trying to lose mass right now.

[smarterthanthat]

Right in time for the pre-summer mass-loss craze! Good luck :)
