Product Code : SCL-PLE-11519
Quick Answer: The Newton’s Second Law Apparatus is a trolley-and-track setup with a pulley, string and weight set for showing that acceleration depends on force and mass. Students vary either one and measure the result to test F = ma.
Last updated: 18 October 2026
Key Features
- Trolley runs on a track pulled by weights over a pulley.
- Force or mass can be varied between runs.
- Shows acceleration proportional to force and inversely proportional to mass.
- Metal track, plastic trolley and steel weights.

How It Is Used
The track is laid on a flat bench and the trolley placed on it, with a string running over the pulley to the weights. When released, the falling weights pull the trolley along; students measure its acceleration, then change the weights or the trolley mass and tabulate the results to check F = ma.
Frequently Asked Questions
What relationship does the Newton’s Second Law Apparatus demonstrate?
That acceleration is directly proportional to the applied force and inversely proportional to the mass, the relationship written as F = ma.
What parts come with the Newton’s Second Law Apparatus?
A trolley, track, pulley, string and weight set.
