Core Pillars (High-Weightage Topics)

3. Conservation Laws

Among the most tested and highest-difficulty topics in JAM.​

Three Conservation Principles:

Linear Momentum Conservation:
When external forces are absent, the total linear momentum of a system remains constant throughout the motion.

Angular Momentum Conservation:
When external torques are absent, the total angular momentum of a system about a point remains constant throughout the motion.

Mechanical Energy Conservation:
For systems with only conservative forces acting, the total mechanical energy, comprising kinetic and potential components, remains constant over time.

Key Applications in JAM:

• Two-dimensional collision analysis​
• Multi-body systems involving explosions or breaks
• Energy dissipation in inelastic collision scenarios
