Laws of Motion – Class 11 Physics NCERT | Newton’s Three Laws, Formulas & Derivations

🧲 Laws of Motion – Class 11 Physics (NCERT) The Laws of Motion were given by Sir Isaac Newton and are fundamental to understanding force, motion, and mechanics in physics. This chapter from Class 11 NCERT explains how forces affect the motion of objects. 📘 Newton's First Law of Motion (Law of Inertia) Statement: A body remains at rest or in uniform motion in a straight line unless acted upon by an external force. 🔹 This law defines inertia – the natural tendency of objects to resist change in their motion. Inertia depends on mass. More mass → more inertia. 📌 Real-Life Example: You fall forward when a bus suddenly stops. 📘 Newton's Second Law of Motion Statement: The rate of change of momentum of an object is directly proportional to the applied force and takes place in the direction of the force. ✅ Derivation: Momentum, p = mv Rate of change of momentum = d(mv)/dt = m dv/dt = ma (if mass is constant) F = ma 📌 This is t...

Space-Time Fabric-what-how-why-science

 Space-Time Fabric: A Complete Overview The concept of space-time fabric originates from Albert Einstein’s General Theory of Relativity (1915). It describes how gravity is not just a force (as Newton thought) but rather the curvature of space and time caused by mass and energy. This explanation transformed our understanding of the universe.

The Four-Dimensional Continuum In classical physics, space and time were seen as separate entities: Space: A three-dimensional framework (length, width, height). Time: A separate, independent dimension that flows uniformly. However, Einstein’s Special Relativity (1905) showed that space and time are deeply linked, forming a four-dimensional continuum called space-time: 1. Three spatial dimensions (X, Y, Z – length, width, height). 2. One time dimension (T – the passage of time). Thus, events in the...
