Right now, you're being pulled toward the centre of the Earth with a force of several hundred Newtons. You don't fall through your chair because it pushes back with EXACTLY the same force. Every force has consequences — they can change an object's speed, direction, or shape. Some forces need contact (friction, tension, air resistance), while others act at a distance like invisible hands (gravity, magnetism, electrostatic). Understanding forces is understanding why ANYTHING moves or stays still!
This introduction covers The Invisible Push and Pull within Forces & Their Effects for GCSE Physics. Revise Forces & Their Effects in Forces for GCSE Physics with 28 exam-style questions and 11 flashcards. This topic shows up very often in GCSE exams, so students should be able to explain it clearly, not just recognise the term. It is section 1 of 13 in this topic. Use this introduction to connect the idea to the wider topic before moving on to questions and flashcards.
