The Newton’s 1st Law Model is a dedicated Physics Science Educational Laboratory Equipment and hands-on apparatus designed to visually demonstrate the fundamental principle of inertia, as articulated in Newton's First Law of Motion.
The law of inertia states that: An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced external force.
This simple, effective device uses a specialized setup—typically featuring a sphere or bulb resting on a cardboard piece which is quickly removed. The apparatus clearly illustrates how:
The object (bulb/sphere) initially at rest attempts to remain at rest (inertia).
When the supporting cardboard is swiftly removed, the object falls straight down due to the unbalanced external force of gravity, demonstrating that its state of motion only changed when a net force acted upon it.
This model is an ideal STEM tool for teaching foundational concepts of motion, force, and inertia in a highly visual and memorable way.
Usage:
Classroom Demonstration: Clearly showing why objects resist changes in their state of motion (e.g., why a passenger lurches forward when a car stops quickly).
Concept Verification: A quick, impactful experiment to introduce the topic of unbalanced forces and the starting point of kinematics.
Interactive Display: An engaging, repeatable experiment that captures audience attention and explains a core physics principle.
