Free-Body Diagrams and Resolving Forces: Scale Drawing Worked Examples | GCSE Physics

Free-body diagrams and forces at angles for GCSE Physics (Higher tier), animated: why a hanging basket pulled sideways hangs still. How to draw a free-body diagram (one object, every force on it, arrows from the object), with a book on a table, a car at a steady speed and a skydiver who has just jumped. Then three worked examples by scale drawing, to scale on screen (1 cm : 10 N): the resultant of 30 N east and 40 N north (tip to tail, and the parallelogram), resolving a 50 N pull at 37° into the part that pulls a sledge along and the part that lifts it, and equilibrium: the basket's three forces close into a triangle. Finishes with four mistakes that cost marks.
