in this resource (video) we are given a wonderful demonstration by a teacher on the functions of p-t graphs, or position-time graphs. This teacher uses visual diagrams to show how he get answers on p-t graphs (ex: slowest, fastest, at rest). I picked this video because it clearly explains how to use a p-t for explaining an object's acceleration. Including these details, he also uses visual explanations for common misconceptions about the acceleration on a p-t graph. There are no errors with this link.
In this resource, we are given a demonstration on what acceleration is. The person explain the video includes acceleration formulas, examples of changing velocity, and the reason why it is vector. I picked this source over others because it gives a visual and audio demonstration of velocity. There are no errors with the link.
In this article, there are two great videos being shown to clarify that Galileo's famous experiment was correct. Both of the videos in this article involve a heavy object and a lighter object; a bowling ball and feather, for example. They include the usage of zero gravity to support the experiment further more. I chose this article because it further explains Galileo's theory: To show that gravity does not make heavier objects fall faster; however, they can fall slower or faster depending on their mass, or surface area. The videos and website functions perfectly.
In this video, we are shown great examples on how to calculate net force and how to use the pythagorean theorem with the parallelogram rule. The person in this video demonstrates how net force vectors are used in everyday life with entertaining examples, like bit of movie scenes. I picked this video because it properly explains how to use net force vectors and the parallelogram rule correctly. He also gives plenty of visuals for the examples he uses on graphs. This resource was chosen over others because of his explanation on how to apply net force vectors and the parallelogram rule to basic understandings of physics.
In this article, it explains how physics is used from computers, trade, and all the way to blood pressure being checked at the doctor's office. Physics is applied to how we function in our daily lives, even if we do not notice it. I picked this resource because it shows how easily it can be applied to anything we do, including the sciences. There were no errors in the link, but it could possibly have minor lag time.
This article gives us a simple, yet informational explanation of science. Science is a basic and logical understanding of the natural world and how it functions. In order to understand these, the scientist also needs to use the scientific method. I picked this article because of its explanations on how the scientific method is properly used and how it can differ for different branches of the scientific community. Including this, the article also has an accurate definition of the scientific method, science, and how the scientific method differs for each branch. Also, it includes how science is not always figuring out an answer, but test for it wrongness.
In this video, we are given a demonstration with visuals on how Erastosthenes measured the Earth with near accuracy. The reason I picked this video was because it demonstrated how easy it is to provide such helpful information, without having to use such complex tools. The video also briefly explains his math formula on how he solved the circumference of the Earth as well. There are no problems with the link.
