Newton's Second Law: F = ma

About This MicroSim

This simulation visualizes the fundamental relationship in classical mechanics: F = ma. Two interactive graphs show how acceleration depends on both force and mass:

  • Graph 1 (Acceleration vs Force): Shows linear relationships for different fixed masses
  • Graph 2 (Acceleration vs Mass): Shows inverse (hyperbolic) relationships for different fixed forces

Key Concepts

  1. Force and Acceleration are Proportional: Doubling the force doubles the acceleration (if mass is constant)
  2. Mass and Acceleration are Inversely Related: Doubling the mass halves the acceleration (if force is constant)
  3. The Equation Links All Three: a = F/m

Learning Objectives

  • Visualize how acceleration depends on force and mass
  • Understand linear vs inverse relationships graphically
  • Apply F = ma to predict motion outcomes
  • Recognize that mass is a measure of "resistance to acceleration"

How to Use

  1. Use the Force slider to change the applied force (0-100 N)
  2. Use the Mass slider to change the object's mass (1-20 kg)
  3. Watch the purple point move on both graphs
  4. Observe the calculated acceleration update in real-time
