📖 Physical Concept & Comprehensive Explanation
Linear momentum measures the quantity of motion contained in an object. When no external unbalanced force acts upon a system, total linear momentum remains conserved before and after collisions.
🎯 High-Yield Revision Points
- ✓Momentum = mass * velocity (p = mv).
- ✓Conserved in isolated systems according to the law of conservation of momentum.
- ✓SI unit is kg*m/s; dimension is [M L T^-1].
