(b) the total velocity change,

That is our change in velocity

We know also that velocity, or let's say the change in velocity, is equal to the final velocity minus the initial velocity.

Well, the change in velocity first of all, is perpendicular to the direction of the velocity itself

Now it could be the velocity doesn't change, if the velocity doesn't change then you're fixed, then you're in an equilibrium, but if the velocity does change, it has to go down.

Acceleration is equal to a change in velocity is equal to a change in velocity over time, or we could say, over change, over a change in time.

Our change in velocity would look like that

It tells us...If you apply a force, it might change the constant velocity but how does it change that constant velocity?

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.

Change in distance is equal to the average velocity.

So what's the change in velocity in this situation?

It would look something like that change in velocity

So the velocity of something is its change in position, ... ... including the direction of its change in postition.

Final velocity is minus 100 meters per second, and then the initial velocity is 0, so the change in velocity is equal to minus 100 meters per second.

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

And then we said, well, the velocity, if we know the distance, the velocity is just the change of the distance with respect to time.

The first thing that changed and is still changing is the velocity of change itself.

The change in velocity is constantly going in the direction of the center of our circle

Velocity X and Velocity Y

The average velocity is just the average of the initial velocity and the final velocity.

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

The change in velocity between those two times was that right over there

So between those two points in time, this is our change in velocity

In the next presentation, I'm just going to keep doing problems, and hopefully you'll realize that everything really just boils down to average velocity change in velocity is acceleration times time, and change in distance is equal to change in time times average velocity, which we all did just now.

This remind ourselves if there was no force acting on this body this comes straight from Newton's 1st Law of motion then the velocity would not change neither the magnitude nor the direction of the velocity will change

So what do you see, if I were to keep drawing more of these change in velocity vectors you would see at this point, the change in velocity would have to be going generally in that direction

This hopefully is intuitive to you, that the change is just the final velocity minus the initial velocity, and that that equals acceleration times time.

The whole reason why I drew these vectors and then translate them over here and drew these change in velocity vectors is to show you that the change in velocity is actually towards the center of this circle

So between this magenta time and this purple time what was the change in velocity?

So the force must be acting in the same direction as this change in velocity

In a quantity of gas, the average velocity of a molecule is determined by temperature, but the velocity of individual molecules change as they collide with one another, gaining and losing kinetic energy.

A relative velocity is the velocity of one body with respect to another.

Assuming no drastic change in velocity, you expect that the 5th position would be over here.

At this point, the change in velocity would have to be going generally in that direction
