5.15 Newton's first law and terminal velocity Newton's first law, inertia, and how falling objects reach terminal velocity when air resistance balances weight, including the velocity-time graph for a skydiver. AQA Edexcel OCR 5.16 Newton's second law Newton's second law F = ma, how acceleration depends on resultant force and mass, and inertial mass (Higher tier). AQA Edexcel OCR 5.17 Required practical: acceleration Required practical: investigate the effect of force and of mass on the acceleration of a trolley using a falling mass, light gates and a data logger. AQA Edexcel OCR 5.18 Newton's third law Newton's third law: pairs of equal and opposite forces that act on different objects, how to identify them, and why they do not cancel out. AQA Edexcel OCR 5.19 Circular motion Why an object moving in a circle at constant speed is accelerating, the centripetal force towards the centre, and what provides it in everyday examples.
