Slowing down.

Slowing down?

They're slowing down.

So, we went down actually.

Launch coming up off the stern, sir. Half speed.

Decelerate.

Decelerate.

The Spider's slowing!

Slow us down.

We should take our foot off the pedal right now, and generally we do.

Come on. Decelerate!

the light's red.

I'm like, Okay, all right, this guy is slowing down,

Don't slow down.

All right. We're down to 0.3896 of light speed.

They've dropped to impulse.

Slow the car down.

The choice in this case is pretty simple.

When they went behind the moon, they were supposed to do a thrusting maneuver to slow them down so they would be captured into lunar orbit.

That would be a bad day, you know, if that happened, so we have to test, because we are deploying this parachute at supersonic speeds.

Running a little hot. Want to open up a speed brake?

And now, since we've just started to slow down, the future echoes are nearer to the present.

Well it's decreasing by 4.

All hands squared away to decelerate.

An object in straight line motion will move forever unless something,

I probably can't do both.

It's providing an unbalanced force in a direction opposite its motion.

That gives us a limit on speed as well.

Sometimes, friction is something to be reduced.

So when the linkage parted, it went the other way. Up instead of down.

I step on the brake.

So our relative velocity to this train is going to be something lower.

From this point, we're going to decelerate from 12,500 miles an hour down to 900 miles an hour.

Quieted the train.

Since that power is less than one, the universe is decelerating.

Dynamically setting the number of particles has been done quite a bit, and it's a good idea under certain circumstances.

Let's see, if we divide both sides by 6 well, let's subtract 100 from both sides.

Because you have all of these air particles that are going to bump into it

Okay, let's slow down here to a stop in preparation for a lefthand turn.

Running it gives us 1 unchanged and 11.

How do they do it?

If there is more matter, there is more gravity and so the, the, the expansion slows faster.

Central has asked me to slow down the harvesters... to ensure you have time to recuperate and get your strength back.

In the first 15 seconds after we deploy the parachute, we'll decelerate from 900 miles an hour to a relatively slow 250 miles an hour.

All right, there's nothing to this. Just tap the brakes a little bit.
