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 ...

ABSTRACT We present the results of a search for cool subdwarfs for which our candidates were drawn from a V−J reduced proper‐motion diagram constructed by Salim & Gould. Kinematic (U, V, and W) and ...

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.
