This simulation is to recreate Walter Fendt's Newton's Second Law applet ( The sim is aligned with the Force Lab in Modelling Instruction. The outcome is for learner to formulate F = ma with experiment conducted with motion sensor, rather than light gate, found in most Singapore secondary and junior colleges science laboratories.

Pre-requisite knowledge
- Kinematics graphs
- Nature of forces
- Understand idea of resultant force
- Effect of gravity on mass, i.e., gravitational force

Investigate how the resultant force on a system affect its acceleration.
