For this article I plan on updating the sources because the sources on the article currently go back to 1966. This is not a major problem because the physics is still the same however because it has been over 40 plus years, there has been new publications and more information on the topic. The first round of business is to add to jerk and jounce because there is only a small paragraph on it. Next I want to focus on velocity and add to the content there and fix what's outdated. Lastly I will go over the displacement section and the introduction to the topic.

Existing paragraph on Instantaneous velocity:

In contrast to an average velocity, referring to the overall motion in a finite time interval, the instantaneous velocity of an object describes the state of motion at a specific point in time. It is defined by letting the length of the time interval  tend to zero, that is, the velocity is the time derivative of the displacement as a function of time.

The magnitude of the instantaneous velocity  is called the instantaneous speed.

Add on to existing paragraph:

The instantaneous velocity equation comes from finding the limit as t approaches 0 of the average velocity. The instantaneous velocity shows the position function with respect to time. From the instantaneous velocity the instantaneous speed can be derived by getting the magnitude of the instantaneous velocity. To calculate the instantaneous velocity you use the equation Ant^n-1 which comes from the position function.

Instantaneous Velocity

This article doesn't have much on displacement so I will go into more depth with that and will show displacement graphically as well. Also, none of the sections include anything on graphs so that will be one of the main things that I will add to this article.

Add to paragraph on displacement

When graphing velocity vs time, the area under the graph would equal the displacement for the object of affection. Displacement is a vector when being compared to distance which is scalar. Another formula to find displacement is Δx = (average velocity)Δt.

There is no mention of free fall and I will definitely be adding a paragraph on that.
