Hey, how you doing?
You want to buy something?
I got a lot of stuff here.
And I got a special today only.
Potential Energy, huh?
I will throw in some potential energy with
any order.
You see this stuff on the shelves here?
The stuff on the highest shelves has more
potential energy
than the stuff on the lower shelves.
Don't believe me?
Here, hold on, hold on.
Look at this state-of-the-art traffic control.
Right now, it's sitting up here on this high
shelf.
Now, if it were to fall, it would be going
fast,
which means it would have a lot of kinetic
energy.
(laughs)
You see?
When it fell down, it had enough kinetic energy
to completely break itself apart.
Um, yeah.
Well, that's the difference between potential
energy and kinetic energy.
Look at this bagel.
Just sitting here.
Not moving, minding its own business, on top
of this ramp.
It's all potential energy, and no kinetic
energy.
And when it gets to the floor, it's all kinetic
energy and no potential energy.
Woo hoo!
And now it has neither, because it's on the
floor and it's not moving.
Five second rule.
And now you know your energy.
So what do you say, you want this thing?
Tell you what, I'll give you a discount,
because you know, it's gently used.
Hey, I'll even throw in this bagel, huh?
Also gently used.
