Hovering Disk - DIY 3D Printed - Frictionless Motion Experiment

thingiverse

The Hovering Disk is a 3d printed device, which demonstrates almost frictionless motion. The air coming from the balloon is moving through a small whole to the bottom of the disk. At the bottom it is distributed all-over to all sides. This constant air stream prevents the disk from touching the ground and the disk therefore starts hovering. See the disk in action:https://youtu.be/wl0n9UZzOhQ To demonstrate the hovering effect use even surfaces like glass or flat tables. Print Settings Printer Brand: MakerBot Printer: MakerBot Replicator+ Rafts: No Supports: No Infill: 30% Notes: No Rafts no support, make sure the print surface is even and does not have any damage. How I Designed This I designed this using Autodesk Inventor, check the video from the description for more information. Overview and Background Teaching about kinematics in physics always needs to include talking about friction. What it is and where the energy goes to. Demonstrating moving objects with friction is easy, since friction is everywhere. But how to demonstrate moving objects with (almost) no friction is hard. Use the "Hovering Disk - DIY 3D Printed - Frictionless Motion Experiment" to demonstrate movements with almost no friction. Lesson Plan and Activity This project acts more like a lessen opening than the main content. Demonstrating the effect of almost no friction will give you a nice introduction into the mechanics of moving objects.
