Quick Answer: The Newton’s Second Law Model is a physics demonstration apparatus that shows how force, mass and acceleration are related, helping students understand F = ma through visible motion.
Last updated: October 2026
Key Features
Demonstrates the relationship between force, mass and acceleration.
Teaching aid for the meaning of F = ma.
Shows how increased force changes acceleration for a given mass.
Shows how increased mass affects acceleration under the same applied force.
Can be used without electrical power unless the supplied model includes timing or sensor accessories.
About This Product
The model is set up on a level bench with a selected mass and applied force, the moving body is released, and its motion response is observed. Trials are then repeated with a different force or mass so students can see how acceleration responds. It is intended for teacher-led demonstrations, supervised student activities and science exhibitions on force and motion. Export supply of the Newton’s Second Law Model can be arranged to laboratories and schools in Sierra Leone, Turkmenistan, Nicaragua, Eritrea and South Korea.
Frequently Asked Questions
Q1. What happens to acceleration when the mass is increased? Under the same applied force, a larger mass gives a smaller acceleration, as F = ma shows. Repeating trials with different masses lets students see this on the model.
