KS3 Forces and Motion Revision Guide by Stanley Tio is a document available to read on EtoBox.

1. Non-contact forces include gravitational force, electrostatic force, and magnetic force. An unbalanced force on an object could cause it to speed up, slow down, or change direction. 2. Resistive forces include friction and air resistance. Friction resists the motion between two surfaces in contact, while air resistance opposes the motion of an object moving through air. 3. The unit used to measure force is the newton (N). A force meter or force gauge is used to measure force. 4. The weight of an obje
