ECZ 2025 GCE SCIENCE P1 QB2 | Velocity Ratio, Work Done & Efficiency (Full Solution)

ECZ 2025 GCE Science P1 Physics Question B2 solved step-by-step. In this lesson we solve a Physics exam question on simple machines (inclined plane) and explain: • Definition of a simple machine • Velocity Ratio of an inclined plane • Work done against gravity • Mechanical Advantage • Efficiency calculation The question involves a ladder used as an inclined plane with a length of 4.5 m and a vertical height of 1.5 m. We show the full working required in ECZ exams so students can learn how to score full marks in Physics calculations. 📚 Topics covered: Simple machines Inclined plane Velocity ratio Mechanical advantage Efficiency This video is helpful for students preparing for: ECZ Grade 12 Physics GCE Physics Science Paper 1 Physics questions Subscribe to KAS BRIGHT MINDS for more past paper solutions and exam preparation lessons.
