Density Tower (Comparison of densities of various liquids, plastic, iron, and gold)
Density Tower A density tower is made by stacking several liquids in one container according to differences in density (mass per unit volume). Liquids with higher density sink to the bottom, while liquids with lower density … more
Pendulum Wave
Pendulum wave A ‘Pendulum wave’ is a collective wave-like phenomenon that appears when pendulums (weights) of different lengths are arranged side by side. Because each pendulum has a different period depending on its length, they oscillate … more
Blocklab – Circular motion simulation
This is a simulation of circular motion (orbital motion) of an object using Blocklab. You can experiment with object motion by applying various variations to the block code.
Blocklab – Parabolic motion simulation
This is a simulation of parabolic motion of an object using Blocklab. You can experiment with parabolic motion of an object by applying various variations to the block code.
Blocklab – Block coding tool
Blocklab is a simulation creation tool built on Google Blockly that lets users assemble blocks to explore a wide range of dynamic experiments. With Blocklab, you can create algorithm-based dynamic simulations intuitively. The simulations you build … more
Pressure, buoyancy, and gravity applied to a balloon
Assume the pressure inside and outside the balloon is equal at 1 atmosphere. For ease of calculation, the volume and mass of the balloon and string are assumed to be zero. Pressure on a Balloon In … more
Video motion analysis (Multi-flash photography, Stroboscope)
This app is Web-based software that converts video footage of an object’s motion into multi-flash photography. This program analyzes the movement of objects captured on video frame by frame. It may not work on Apple devices … more
Buoyancy comparison
Why is the submerged volume important to understand buoyancy? It is so famous that the 3rd-century Greek philosopher Archimedes shouted “Eureka!” and ran out of the bathhouse naked. （What did Archimedes find out? – Quotations from … more
Solar system making
Movement of the planets of the solar system The planets in the solar system receive gravity from the Sun and revolve around it due to this gravity. The following is a table of the orbital radius … more
