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
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
Drinks in a straw aren’t pulled, they’re pushed. When we say ‘straw,’ most people picture liquid being sucked upward. But scientifically, that’s not what happens. The liquid doesn’t rise because of suction; it rises because the … more
Pressure is defined as the force applied per unit area. When the same force is applied to two different surfaces, the pressure depends on the size of the area: the larger the area, the smaller the … more
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
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
