So this is a simple distance is equal to rate times time problem.

Velocity really is just distance divided by time, or actually, change in distance divided by times change in time or, change in distance divided by change in times is velocity.

Well, the velocity is equal to distance divided by time.

So I've traveled the distance of a wavelength, and how long did it take me to travel that distance?

It's distance divided by time, right?

And position, or distance, is just equal to velocity times time.

After t sub nought seconds, right?

This is change in time and change in distance.

So s is equal to distance, and then t is equal to time.

So they tell us the distance 720 meters and so we just have to figure out the time.

So if we know how far we've traveled, and we know how long it took us, it took us one period, how can we figure out the velocity?

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

So, the change in distance is equal to the average velocity times time.

The dimensional analysis yields units of distance squared per time squared.

You could say that my average velocity equals just change in distance divided by change in times.

But actually, we measure distances using time almost every day. How far is it from your house to the store?

If we do, then it just turns out to the final distance is equal to the average velocity times the final time, but

You get distance is equal to change in time, times factoring out the 1 2.

Some time people will write a triangle or delta there for change in time.

So you can start from very common sense things rate as distance divided by time and then just manipulate it to get other common sense things so we could've done it here.

So if you wanted to know how far you traveled after t sub zero seconds, you'd essentially get, or an approximation would be, the sum of all of these areas.

Maybe later on we'll do situations where we're not starting at time 0, or distance 0, and in that case, we will have to be a little more formal and say change in distance is equal to average velocity the change in time.

We could have rewritten this as the change in distance is equal to the average velocity times the change in time.

So it would be that distance plus that distance plus that distance plus that distance.

We know that I'll write it slightly different this time the change in distance over the change in time is equal to the average velocity.

And we learned that the focus, the focal distance or the distance from the central of the ellipse, which is this distance right here that focal distance is just the square root of the difference of these two numbers.

This magenta distance minus this light blue distance.

let's say that we accelerate at 1 m s 2...and we do it for so the change in time is going to be 5 seconds and my question to you is how far have we traveled?

This distance squared plus this distance squared is going to equal that distance squared.

So if this distance is the same as this distance, then the magenta distance minus this blue distance is going to be equal to this green distance.

This distance is the same distance as this distance right there.

In other words, the distance between any two given points of a rigid body remains constant in time regardless of external forces exerted on it.

So what is the distance from A to C?

The absolute value is really just the distance of x from 0. distance from 0

It's the distance from 0.

LAWRENCE

So that distance is the same as that distance.

This distance is the distance squared.

This distance is going to be equal to that distance.

That this distance plus this distance over here, is going to be equal to some constant number.

This distance right here is 3, this distance right here is 3, this distance right here is 2, this distance right here is 2.

The reason why I have change in distance here, or change in time, is that I'm not assuming necessarily that we're starting off at the point 0 or at time 0.

And so if this is at distance 0, we could call this distance out here distance d.

That this distance is equal to this distance
