Newton's Second Law of Motion

Force equals the rate of change of momentum (F = ma), the quantitative core of classical dynamics.

Core Principles & Analysis

• Newton originally stated it as force equaling the rate of change of momentum.
• In momentum form F = dp/dt it carries over into special relativity.
• Defines the newton: the force giving a 1 kg mass an acceleration of 1 m/s².
