Forces & Motion KS3 is a five-mission Year 8 activity book mapped to the DfE National Curriculum for KS3 physics (forces). Learners sort contact forces from non-contact forces, decide whether forces are balanced or unbalanced and find the resultant force on a line, measure force in newtons with a newton-meter, calculate weight from mass using W = m × g (g = 10 N/kg), work out speed with speed = distance ÷ time, and investigate friction, air resistance, Hooke’s law and streamlining. Every question is auto-marked on screen, or the whole book can be printed with a full answer key. Includes teacher, parent and pupil notes and is fully SEND-friendly with high-contrast and large-text modes.
