Introduction to Newtonian Rotational Motion and Moment of Inertia: Understanding rotational motion and moment of inertia is essential in physics, particularly when dealing with objects that rotate. Sir Isaac Newton’s laws of motion, which describe the relationship between the motion of an object and the forces acting on it, are extended to cover rotational motion. … Read more
Mass Introduction: Mass is a fundamental property of matter that quantifies the amount of substance in an object. It is a scalar quantity and is typically measured in units such as kilograms (kg) or grams (g). The mass of an object is constant and independent of its location, meaning it is the same regardless of … Read more
A frictionless pulley is a mechanical device that allows a flexible material, such as a rope or belt, to move over it with minimal resistance. The absence of friction enables the pulley to rotate freely without dissipating energy due to frictional forces. In scenarios where a mass is connected to a pulley system, the mass … Read more
