Slowing down.

Slowing down?

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

Decelerate.

Decelerate.

They're slowing down.

So, we went down actually.

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

Slow us down.

They've dropped to impulse.

The Spider's slowing!

Slow the car down.

The choice in this case is pretty simple.

Come on. Decelerate!

the light's red.

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

All hands squared away to decelerate.

Don't slow down.

I probably can't do both.

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

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

Well it's decreasing by 4.

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

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

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.

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

That gives us a limit on speed as well.

Running it gives us 1 unchanged and 11.

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

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

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.

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

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

Quieted the train.

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

Japan's foreign aid is decreasing in part because of an economic slowdown at home.

That's because we're, kind of, where the velocity of train A is being eaten away by the velocity of B.

Sometimes, friction is something to be reduced.

With 1425 meters elevation the air is getting thinner

How do they do it?

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

I step on the brake.
