IGCSE Forces & Motion: Newton's Laws, Friction and Free-Body Diagrams

Forces and motion is the largest topic in IGCSE Physics and carries significant weight in the exam. I help students develop a strong intuition for Newton's laws, draw accurate free-body diagrams and solve force problems systematically.

Newton's Laws in IGCSE Physics

Newton's three laws form the backbone of IGCSE mechanics. I ensure students can state each law precisely, apply F = ma to calculate resultant forces and accelerations, and explain action-reaction pairs correctly — a common area where marks are lost through imprecise language.

Friction, Air Resistance and Terminal Velocity

Understanding friction and air resistance is essential for IGCSE exam success. I help students explain how terminal velocity is reached, interpret velocity-time graphs for falling objects and calculate stopping distances. These topics frequently appear as extended-response questions worth significant marks.
