Newton's Third Law of Motion

For every action there is an equal and opposite reaction: forces always come in matched pairs.

Core Principles & Analysis

• Explains rocket propulsion: exhaust expelled backward thrusts the rocket forward.
• Equivalent to the conservation of momentum in isolated systems.
• Action-reaction pairs act on different bodies, so they never cancel each other out.

Specifications & Metrics

• SYMBOL: F_A = -F_B
