classroom experiment: terminal velocity with relation to portals

preview_player
Показать описание
A more in depth analysis:

Portals automatically drop your velocity to about 7.8 u/s (or 1000 game units/s) as you go through them, which is why your terminal velocity drops when you go through portals more often. Every time you hit a portal, your speed drops to 7.8 u/s. If you have less distance to fall after your speed drops, your speed has less time to increase. In the longer drops, you have more time to pick up speed, meaning your terminal velocity, as measured in this experiment, will be higher.

This video is meant to describe a way to quickly and easily run experiments in a classroom. Without knowing that portals affect your velocity ahead of time, this experiment would give students a strong indication that something weird is going on and the relationship between portals and velocity is worth investigating.

Console Commands:
sv_cheats 1 (must be done first but only has to be done once)
host_timescale 0.001 (slows time to 1/1000 speed)
host_timescale 1 (brings time back to normal)

Very impressive, I had a feeling we'd see something like this in the future.

It's amazing how science can relate to video games. I once calculated the MPH of a rail cart in Minecraft. I have also found the fire rate of a weapon by recording multiple fires, then using the sound file to extract the times and fine the average (it was right).

I might have to poke my head back into this channel on a regular basis.

I found this very interesting! I'm sharing this to all my friends!

I've barely thought about anything involving physics in my life, but spent this 5:33 intrigued.

Using game worlds to learn physics is a delightful idea. And just think of years down the road when the tech has come a ways beyond this.

try to imagine the gravity field line going through the portal, it slows you down because in the experiment, there a gravitational pull towards the blue portal, which slow you down a little bit when you go pass it, if you got two really close portal(like directly above and below) you should go really slow and looks like floating

Why can't MY teachers use this?!

It is a fascinating science, was just discussing this today .
My question is can Terminal Veloctiy be Measured with out a point of Start or Stop .And what force in the Universe can Stop an object at terminal Velocity as you did in your demonstration .

Show this to them! Maybe you'll change their minds :)
