No and here's your smoke too sure brought to you
- 00:04
by diving boards They provide us with a great opportunity
- 00:07
to look really cool Four really un cool A person
- 00:12
standing still at the top of a very tall diving

board has a lot of which and here the potential

answers i'm gonna go I don't see in there we
- 00:22
might not think there's any energy involved when we're standing
- 00:24
still on a diving board and oh how wrong we
- 00:27
would be if it takes a lot of energy to
- 00:29
hold back are hysterical tears when we see how high
- 00:31
up we are It also takes a lot of energy
- 00:33
just climbing the darn ladder Seriously anyone else ready for
- 00:36
a nap Just us So where does that energy go
- 00:40
Well it'll take the same amount of energy to come
- 00:42
down as it will to come up And that type
- 00:45
of energy is called potential energy because nothing is happening
- 00:48
yet but well it could essentially it's in storage So
- 00:52
the correct answer is b and because we don't feel
- 00:54
like jumping just yet Let's make sure the rest of
- 00:56
the answers are incorrect Just teo you know past time
- 00:59
Not that we're scared or anything Once the dive star's
- 01:01
gravity we'll do what it does best The energy use
- 01:04
while we're in motion is called kinetic energy but if
- 01:07
there's no motion there's no kinetic energy so is incorrect
- 01:11
Dissipated energy is energy That's lost well usually is heat
- 01:14
When we fall through the air we create friction This
- 01:17
means that some of the kinetic energy becomes heat which
- 01:20
dissipates into the air as we fall but that can
- 01:23
only happen when in motion So it's not the right
- 01:25
choice here And while we might be a little scared
- 01:28
on top of the diving board nervous energy isn't really
- 01:30
a thing in the physical sciences will leave that to
- 01:33
psychiatry is definitely not right So yeah our answer is
- 01:37
definitely be We wish we could do graceful dives like
- 01:39
these when we try though all the energy is usually 00:01:42.864 --> [endTime] converted into belly flops
