In a down to earth manner, Allian explains Newton's third law of motion. Not only that, he also clarifies some common misconceptions about the third law. However, this article is not the most objective out there.
Mr. Andersen reviews the different types of forces and applies them to different situations. He also demonstrates how to draw free body diagrams to illustrate these forces. In accordance to Newton's second law (F=ma), it is an imbalance of forces that causes objects to move.
Mr. Andersen utilizes different visuals to teach students about how to interpret a position - time graph with a constant velocity. One of them, The Moving Man, demonstrates how the slope of a line represents the velocity change with the displacement (position from starting point) and where the time and position lie. The position lies on the X axis and the time lies on the Y axis. t
This article effectively explains what the first law of motion is. Not only does it explain, but also provides an example of the first law and some experiments one could try themselves at home. However, this article could benefit from more than one example.
Clearly explains what physics is, why it's relevant, and why we study it. I thought this was a good resource because it not only expands on the subject, but it does so in a down-to-earth way that anyone can understand. Closed captions are needed because Professor Naylor's voice is a bit hard to understand without them.
