The setup includes: M1 → A hanging mass M2 → A block on an inclined plane (45° angle) A frictionless pulley at the top A string connecting M1 and M2 What This Model Shows 1) Newton’s Second Law (F = ma) Newton’s Second Law states that: Acceleration of an object depends on the total force acting on it and its mass. In this model: When M1 is heavier than M2’s component on the slope, the system accelerates, pulling M2 up or down the incline. The greater the difference in mass, the greater the acceleration. 2) Motion on an Inclined Plane The block M2 slides on a 45° slope. On an incline, only part of the weight helps in movement: Weight component down the incline = M2 × g × sin(45°) This shows how slopes reduce effective force. 3) Moment of Inertia (Rotational Resistance) The pulley is marked “frictionless”, meaning: It rotates freely It does not resist motion There is negligible moment of inertia This helps students understand: A system with less rotational resistance moves faster If the pulley had more inertia, acceleration would be slower Thus, moment of inertia affects rotational motion, just like mass governs linear motion. How the Model Works (Simple Explanation) When you release M1, it moves downward because of gravity. The string pulls M2 along the incline. The acceleration depends on: Difference in masses (M1 and M2) Slope angle (45°) Pulley resistance (almost zero) This demonstrates Newton’s Second Law, because: More force or less mass → more acceleration Less force or more mass → less acceleration Disclaimer : Use of this Video information : The information in this video is for educational purposes only and is not intended to be a substitute for expert advice in the appropriate subject matters.
