I saw it again. This time it was an introduction to an interesting online look at introductory physics. I was excited---but then, I wasn't so excited. Right there in the first video they talked about ...

Physics, particularly forces and motion, can be challenging. By observing everyday motion, conducting simple experiments, and understanding Newton's laws in plain language, the concepts become more ...

Do you need some practice with force diagrams for your introductory (or advanced) physics course? Here are three questions (and the last one is awesome) about the motion of a bike as it is pulled.

THIS little work, in spite of its ponderous and somewhat ambiguous title, is a useful and workmanlike collection of curves from which may be obtained the value of the mean velocity v in the empirical ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...
