Machine Efficiency & Mechanical Advantage | Physics Explained

Описание: What is the connection between Machine Efficiency and Mechanical Advantage (M.A.)? 🔑 In this video, we explain both concepts with clear formulas, step-by-step examples, and exam-style problems — perfect for WAEC, NECO, and JAMB Physics students.

📐 In this video, you’ll learn:

Definition of a Machine in Physics

Mechanical Advantage (M.A.):


M.A. = \frac{\text{Load}}{\text{Effort}}

Formula:


Efficiency (\%) = \frac{M.A.}{V.R.} \times 100

Real-life applications in pulleys, levers, gears, and inclined planes

Solved WAEC/NECO/JAMB-style Physics questions


🎯 Perfect for:

WAEC, NECO, and JAMB Physics students

Secondary school learners

Anyone studying Work, Energy, Power, and Machines


💡 Mastering M.A. and Efficiency helps you calculate machine performance and understand how real machines reduce effort.
