Acceleration time

Appearance time

And what I want to show you in this video that is in general, if you plot velocity, the magnitude of velocity ...so you could say speed versus time... or let me just stay with the magnitude of the velocity versus time the area under that curve is going to be the distance traveled (or the displacement) because displacement is just the velocity times the change in time so if you just take out a rectangle right over there

And you would say, it takes 15 seconds.

You get vbt minus vct is equal to 300.

And in 5 seconds and they give us that information.

This is close to but does not have to be equal to the age of the Universe at that time, T0.

So the column will move its distance is equal to the column's rate, velocity.

Although I'm sure you know this formula.

We've broken the light barrier 22 hours early.

So, you know, even sex is on a stopwatch these days.

So we say 84 is equal to velocity times your initial velocity times time.

Let's say we know that it's time, t.

Arnold, we're going to hit light speed in 24 hours,

By the time we see what is ahead of us and react to it time times velocity equals distance equals one fifth of a second times 25,000 miles per hour equals 1.4 miles

So what is the actual distance?

She's going at the same velocity, but it takes her 20 minutes.

He was going ten miles an hour on the highway.

At our current speed, 8.2 hours.

Airspeed, 300.

So the slope over here might be 23... whatever miles per hour, but instantaneous, his fastest poin in this 9.58 seconds is closer to 30 miles per hour.

So if we're going at 1000km hour going at 1000km hour, it would take us

So this goes straight back to the, the standard to distance is equal to rate times time.

The train ran at the rate of 500 miles an hour.

The train was going 500 miles per hour.

The train was moving at 500 miles per hour.

A fast walker can walk six kilometers in an hour.

And this key word average is interesting.

So maybe I go, every half second so on this half second, I was going at this velocity and I go at that velocity for half a second velocity times the time will give me the displacement and then I do it for the next half second same exact idea here, it'll give me the displacement so on and so forth

So if you were to travel at the speed of a bullet, speed of a bullet, or the speed of a jet liner, 1000km h it would take you 40 hours to circumnavigate the Earth 40 hours to go around the Earth...

So it's 4360 hours to circumnavigate the Sun, going at the speed of a bullet, or a jet liner!

One minute, 26.5 seconds 108.5 miles an hour.

That's how fast he's approaching the back of the column.

See it uncurl and then peel these toes.

They just said that the officer is going 3 times as fast, but we don't know absolute velocities.

Fifty, sixty miles per hour if they ever got out in the open.

Time will pass quite quickly when you read something.

95. 1 miles an hour.

Whoa! Looks like he's going 90 mph standing still.

Well, we clocked the TRex at 32 miles an hour.

700 miles an hour. 700 miles an hour.

And if you remember the idea of slope from your Algebra 1 class that's exactly what acceleration is, in this diagram right over here

OK, so let's put in some numbers.

In the last typhoon, the wind blew at over 200 kilometers per hour!

look at, they're just sitting there nonchalantly.
