That's our average velocity, velocity average.

Well the velocity is just, what's velocity?

The average velocity is just the initial velocity plus the final velocity over 2.

Velocity

Velocity!

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

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

It's not the velocity. It's the magnitude of velocity

Angular velocity

Max velocity

Input velocity

Geocentric velocity

Topocentric velocity

Velocity X

Velocity Y

Times velocity.

Constant velocity

It is our final vertical velocity, minus our initial vertical velocity.

The height here is my final velocity minus my initial velocity.

Achieving Escape Velocity

(e) Impact velocity

Y angular velocity

Z angular velocity

So the velocity.

If you think about its velocity, the magnitude of its velocity is constant.

So the derivative of distance is velocity, the antiderivative of velocity is distance.

So that equals 5.25. plus 49.85 times the skater's velocity, the final velocity.

Now, since the velocity is changing, we're going to say the average velocity.

And let me plot its velocity against time so this is my velocity

We know the average velocity is equal to the final velocity plus the initial velocity over 2, and this assumes acceleration is constant.

And the average velocity...if your acceleration is constant... if and only if your acceleration is constant then your average velocity will be the average of your final velocity and your initial velocity and so in this situation, what is our average velocity? well our average velocity, let's do it in m s is going to be our final velocity, which is (let me calculate it down here) so our average velocity in this example

Note ΔV velocity variation.

What's the average velocity?

It's new velocity vector

That's my initial velocity.

That's our average velocity.

Its velocity is changed.

So we say 84 is equal to velocity times your initial velocity times time.

So, lets figure out the final velocity, the vertical and horizontal components of that final velocity, and then we can reconstruct the total final velocity.

If his initial velocity is negative 5 feet per second, his final velocity is this.

And since this velocity is always changing, we want to figure out the instantaneous velocity.

That is the output velocity.

So what's the velocity vector?

That is our velocity vector.

Change in velocity over time.
