Storyboard Beskrivelse
Visual description of the definition of the kilogram
Storyboard Tekst
PLANCK'S GYM
Which barbell are you going to bench?
6.626 x 10^-34 J x s
1 Kg
It doesn't make a difference, they weigh the same.
What do you mean?
6.626 x 10^-34 J x s
They weigh the same because scientists just changed the definition of the kilogram from a physical weight to Planck's constant.
1 Kg
Why would they need to change it from a physical weight?
6.626 x 10^-34 J x s
A physical weight slowly loses mass over time. You can't get buff lifting weights that weigh less each time.
1 Kg
They want to change the second to make atomic clocks more accurate.
What other units are scientists changing?
1 Kg
6.626 x 10^-34 J x s
Nope, we'll have the same amount of time as always to get swole.
Does that mean there is more time in a day?
1 Kg
6.626 x 10^-34 J x s
