The Free Fall model allows the user to examine the motion of an object in freefall. This is simply one-dimensional motion (vertical motion) under the influence of gravity.

4### 2-3 Instantaneouos and Average

- ToggleBelow is an accurate scatter plot of your data. Despite what the instructions suggest, you do not know what the graph of

looks like. However, you can imagine a curve that models the data points. This curve is the purple curve shown in the diagram.

Now, the instantaneous velocity at

is approximately the slope of the tangent line shown above (approximate because the tangent line shown is tangent to the blue curve and the blue curve approximates the graph of).

How can you estimate this slope using the tabular data? Well, it's essentially what you did: estimate the slope of the tangent line, and hence the instantaneous velocity at

, with the slope of a secant line between two of the given data points. (Note, please, you only need to estimate the slope of the line; you do not need to find the equation of the tangent line.)

But, you cannot select those two points randomly, this may give a bad estimate. In particular, you want

to be "between" or one of the two points that you choose. Looking at the picture, it should be clear that the best points to choose are and.

So, we will estimate the instantaneous velocity with the average velocity over

(the average velocity over is the slope of the line connecting the points and).
