This is a worksheet to practice force diagrams (free body diagrams). The worksheet includes objects at rest, moving at constant velocities, and accelerating. The worksheet also includes situations with friction (both kinetic and static) and a set of situations where Newton's Third Law could be used. There are 10 situations given. Answer key and teacher's notes are provided. This was originally intended for a 9th grade physical science class, but could be used in middle school. It does not involve any objects on inclines or forces at angles but this could be used in physics as well. Please let me know if you have questions!!
