Product Overview
The Newtonian Demo Set is a curated collection of hands-on apparatus designed to vividly demonstrate Newton’s Laws of Motion in classroom or lecture settings. Ideal for physics educators, this set offers clear, interactive demonstrations of inertia, force, acceleration, and action-reaction principles—making abstract concepts easy to observe and understand.
Inertia Apparatus – Ball and Card
Demonstrate inertia and Newton's First Law of Motion with this classic device. The apparatus includes a base, spring, receiver post, and a plastic ball. To operate, place the ball on a brightly colored acrylic square (green for high visibility), which rests atop the post. When the metal bar—acting as a spring—is pulled back and released, it swiftly knocks the acrylic square away, while the ball remains on the post due to inertia. This is similar to the tablecloth trick where dishes stay in place as the cloth is pulled out. Ideal for large group demonstrations. Dimensions (w × d × h): 180 × 130 × 135 mm.
Second Law of Motion Apparatus
Illustrate Newton's Second Law by showing that a horizontally projected object and a freely falling object drop at the same rate under gravity. The setup features a spring-loaded metal launcher and two steel balls. When triggered, one ball is propelled horizontally while the other drops straight down—both hitting the ground at the same time. The launcher includes three tension settings for varying horizontal distances. The apparatus is supported on a metal rod for adjustable height.
Fan Rocket – Action & Reaction
Perfect for demonstrating Newton's Third Law: action and reaction. This battery-powered "rocket" is mounted on a ball-bearing steel rod with a large, stable base. A removable circular sail determines its motion: with the sail, the rocket remains stationary; without it, the rocket circles the rod. A push-button switch changes direction—clockwise or counterclockwise. Requires two AA batteries (not included).
