1. The Core Principle
Whenever Object A exerts a force on Object B, Object B simultaneously exerts an equal in magnitude and opposite in direction force on Object A.
Action Force = Equal & Opposite Reaction Force
2. Why Acceleration Differs
Even though the interaction forces are identical in magnitude, the resulting accelerations depend inversely on the mass of each cart.
Acceleration is Inversely Proportional to Mass
A cart with 5x the mass will experience 1/5th the acceleration!
3. Conservation of Momentum
Because the net external force on the two-cart system is zero, the total system momentum remains perfectly conserved throughout motion.
Total System Momentum = Constant
