Dialogue: 0,0:01:03.06,0:01:07.15,Default,,0000,0000,0000,,said that force is mass\Ntimes acceleration,

Dialogue: 0,0:01:11.82,0:01:14.40,Default,,0000,0000,0000,,And that's why we\Nmeasure force in Newtons.

Dialogue: 0,0:01:18.55,0:01:21.13,Default,,0000,0000,0000,,(gentle music)
Dialogue: 0,0:01:22.23,0:01:24.99,Default,,0000,0000,0000,,So we measure mass in kilograms,
Dialogue: 0,0:01:27.56,0:01:32.56,Default,,0000,0000,0000,,and we measure acceleration\Nin meters per second squared.
Dialogue: 0,0:01:35.48,0:01:40.06,Default,,0000,0000,0000,,Then we should measure force in Newtons.

Dialogue: 0,0:01:42.96,0:01:45.43,Default,,0000,0000,0000,,So to put this formula into perspective,
Dialogue: 0,0:01:45.43,0:01:48.99,Default,,0000,0000,0000,,it's like one Newton, this guy,

Dialogue: 0,0:01:52.25,0:01:55.33,Default,,0000,0000,0000,,and that makes that mass to accelerate

Dialogue: 0,0:01:58.87,0:02:01.56,Default,,0000,0000,0000,,So here I have a carabiner.

Dialogue: 0,0:02:06.47,0:02:08.84,Default,,0000,0000,0000,,the question is, what's\Nthe force right now

Dialogue: 0,0:02:10.11,0:02:12.47,Default,,0000,0000,0000,,So if we look back to the formula,
Dialogue: 0,0:02:12.47,0:02:15.92,Default,,0000,0000,0000,,we can say that mass is my mass
Dialogue: 0,0:02:15.92,0:02:18.54,Default,,0000,0000,0000,,multiplied by acceleration.
Dialogue: 0,0:02:19.35,0:02:21.30,Default,,0000,0000,0000,,What acceleration?\NI'm hanging on a tree.

Dialogue: 0,0:02:29.88,0:02:33.79,Default,,0000,0000,0000,,Look, so you've probably\Nseen this experiment before,

Dialogue: 0,0:02:37.50,0:02:39.41,Default,,0000,0000,0000,,And the question is, if I let go

Dialogue: 0,0:02:55.91,0:02:58.56,Default,,0000,0000,0000,,So yes, they fell at the same time,
Dialogue: 0,0:02:58.56,0:03:00.27,Default,,0000,0000,0000,,because that's what gravity does,
Dialogue: 0,0:03:00.27,0:03:04.37,Default,,0000,0000,0000,,it makes objects fall at\Nexactly the same acceleration
Dialogue: 0,0:03:04.37,0:03:08.80,Default,,0000,0000,0000,,of 9.8 meters per second per second.
Dialogue: 0,0:03:15.79,0:03:18.51,Default,,0000,0000,0000,,So then I'm hanging on this carabiner,
Dialogue: 0,0:03:18.51,0:03:20.39,Default,,0000,0000,0000,,gravity is pulling me down.
Dialogue: 0,0:03:20.39,0:03:23.29,Default,,0000,0000,0000,,But in order for me to not move down,
Dialogue: 0,0:03:23.29,0:03:27.27,Default,,0000,0000,0000,,there must be opposite force,\Nwhich would be pulling me up.
Dialogue: 0,0:03:27.27,0:03:29.49,Default,,0000,0000,0000,,Here I have a spring.

Dialogue: 0,0:03:32.67,0:03:35.37,Default,,0000,0000,0000,,the spring is pulling the rock up.
Dialogue: 0,0:03:35.37,0:03:39.23,Default,,0000,0000,0000,,So the carabiner is actually\Nlike a very, very stiff spring,
Dialogue: 0,0:03:39.23,0:03:41.15,Default,,0000,0000,0000,,which is pulling me up.
Dialogue: 0,0:03:41.15,0:03:44.27,Default,,0000,0000,0000,,The molecules of the carabiner\Nwhen I'm hanging on it
Dialogue: 0,0:03:44.27,0:03:46.05,Default,,0000,0000,0000,,are being spread apart,
Dialogue: 0,0:03:46.05,0:03:49.85,Default,,0000,0000,0000,,but they like to stay\Ntogether, so they pull back.
Dialogue: 0,0:03:49.85,0:03:52.52,Default,,0000,0000,0000,,You can't see this\Nexpansion of the *carabiner

Dialogue: 0,0:04:02.21,0:04:04.87,Default,,0000,0000,0000,,And so it turns out that this carabiner
Dialogue: 0,0:04:04.87,0:04:08.08,Default,,0000,0000,0000,,has to accelerate my weight up
Dialogue: 0,0:04:08.08,0:04:12.68,Default,,0000,0000,0000,,at the same 9.8 meters per second squared,
Dialogue: 0,0:04:12.68,0:04:16.29,Default,,0000,0000,0000,,which turns out to be about 600 Newtons.
Dialogue: 0,0:04:16.29,0:04:21.29,Default,,0000,0000,0000,,Yep, 600 of these need to\Nhold one skinny guy like me.
Dialogue: 0,0:04:28.80,0:04:32.21,Default,,0000,0000,0000,,Okay, moving on, this carabiner says
Dialogue: 0,0:04:32.21,0:04:37.21,Default,,0000,0000,0000,,that it can hold up to 26 kilonewtons.
Dialogue: 0,0:04:37.57,0:04:41.00,Default,,0000,0000,0000,,Kilonewton is basically\Na thousand Newtons.
Dialogue: 0,0:04:41.00,0:04:45.48,Default,,0000,0000,0000,,So it means that it\Ncould hold about 40 me.
Dialogue: 0,0:04:46.65,0:04:48.61,Default,,0000,0000,0000,,I wish I would have a clone machine,

Dialogue: 0,0:16:36.86,0:16:39.13,Default,,0000,0000,0000,,if the climber is really high up,

Dialogue: 0,0:16:41.70,0:16:44.93,Default,,0000,0000,0000,,So as long as he doesn't\Nfall onto something,
Dialogue: 0,0:16:44.93,0:16:49.22,Default,,0000,0000,0000,,the fall will be soft, no\Nmatter how you belay that.
Dialogue: 0,0:16:49.22,0:16:51.96,Default,,0000,0000,0000,,However, if the climber is not so high,
Dialogue: 0,0:16:51.96,0:16:54.79,Default,,0000,0000,0000,,he doesn't have so much\Nrope to absorb the fall,
Dialogue: 0,0:16:54.79,0:16:59.68,Default,,0000,0000,0000,,then soft dynamic belaying\Nis really important.

Dialogue: 0,0:17:11.30,0:17:13.71,Default,,0000,0000,0000,,'cause the more friction you have,
Dialogue: 0,0:17:13.71,0:17:17.00,Default,,0000,0000,0000,,the harder the fall for\Nthe climber will be.

Dialogue: 0,0:17:36.33,0:17:39.74,Default,,0000,0000,0000,,the rope close to the\Nclimber stretches normally,
Dialogue: 0,0:17:39.74,0:17:43.96,Default,,0000,0000,0000,,but the rope closer to belayer\Ndoesn't stretch that much.
Dialogue: 0,0:17:43.96,0:17:46.77,Default,,0000,0000,0000,,It's like having shorter\Nrope and heavier belayer

Dialogue: 0,0:17:47.82,0:17:50.23,Default,,0000,0000,0000,,And although the force to the harness
