In today's video I cover a basic physics definition of a "force", as well as describing and providing examples of contact forces (e.g. friction) and non-contact forces.
Non-contact forces covered in this video are magnetism, static electricity and gravity.
Also included are explanations on how magnets work, what causes static electricity, and how mass and distance affect gravity.
