Engineering lesson 9: Forces: push, pull and gravity · Set 735 · 40 questions
TalentJR

Engineer's tip (Add same way, subtract opposite): Push moves away, pull moves towards; force is measured in newtons (N). Same direction: add. Opposite directions: bigger − smaller, towards the bigger. Weight (N) ≈ mass (kg) × 10.
