In physics, we talk about two types of motion.

Every body persists in, either being in the state at rest, or moving uniformly straight foward.

Move a Line

Move a Half Line

But the spin can speed up.

Because on some level it is super, duper obvious, but on a whole other level it is completely not obvious

You can see shifting the y intercept up just shifts the line straight up.

Reflect in this line

And you do that just by the y intercept.

A nice visual composition of symmetry.

It's got straight lines.

Lines

Straight

Right

Line

So rise we went down by negative four, we ran three, and you can keep doing that on the line and you'll keep ending up on the line.

This was my little bit of bio mimicry.

A line constructed through a point, perpendicular to another line or segment.

And let's say we have this other line over here.

His body would have gone on for ages if the train hadn't hit a stretch of track that curved.

Command line switches

Okay.

But I think this part is obvious something that's at rest will stay at rest unless it is being acted on by an unbalanced force

Let's do one more of these.

The line of 25.2 0.67x y.

Orthogonal to this line?

They're going to hurt each other.

And I'll just call that line L .

The line tangent to a curve

It's smaller than tolerance, and tolerance was set about to 0.001.

Adds the selection in the line edit to the list

Invalid command line switch! Backslash cannot be the last character

Invalid command line switch! Unclosed quotation mark!

Command line is empty

So this is a valid function.

As the crow flies ?

So here's a line that intersects both of them. Let me draw it a bit near than that.

A line constructed through a point, and parallel to another line or segment

Oh, I distracted very easily.

The second type, spin, involves an object rotating, or turning on its axis in place.
