Newton’s 2nd Law Model

Newton’s 2nd Law Model – Force, Mass & Acceleration Demonstration Apparatus for Physics Lab | Manufactured by Samtech Instruments

The Newton’s 2nd Law Model is a physics demonstration apparatus designed to verify Newton’s Second Law of Motion (F = ma). This model helps students understand the relationship between force, mass, and acceleration through practical experimentation.

Ideal for school physics laboratories, STEM learning, and classroom demonstrations, the model provides hands‑on understanding of motion principles.

What Is Newton’s 2nd Law Model?

The Newton’s 2nd Law Model typically consists of a trolley mounted on a base, connected to a pulley and hanging weights. When weights are added, force increases and the trolley accelerates, demonstrating that acceleration is directly proportional to force and inversely proportional to mass.

Students can vary mass and force to observe changes in motion.
