I mean light is travels at a pretty constant speed, doesn't it?

How far will a plane go in four hours that has a constant speed of five hundred miles per hour?

And I was to do this task at a constant steady speed.

The lift is moving at a constant speed, while more or fewer people get on and off.

Z-82 had turned around once more and was racing with constant speed toward its target.

We think time is a long, straight train ride at constant speed.

Would it go on by itself forever in a straight line at a constant speed?

For example older physics could not explain the constant speed of light.

Although the object has a constant speed, its direction is always changing.

You just push through heavy wind while going down at a constant speed.
