Blocklab – Parabolic motion
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.
Mechanics Simulation
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
Video Motion Analysis (Screen Pointing)
Range X min X max Y min Y max This app is a web-based software that analyzes the motion of objects recorded in video frame by frame. This program analyzes the movement of objects captured on … more
Webcam Movement Analysis (on the table)
Try pushing an imaginary ball placed on the table with your finger. If your PC doesn’t have a camera, it won’t work. When the web browser asks for access to the camera, please allow it. (Personal … more
Movement of an object suspended from a pulley
Movement on the pulley Two objects are connected by a string on a fixed, frictionless pulley and are moving together. In this case, the mass of the string and pulley is ignored. Since tension \(T\) and … more
Gravity Simulator
This simulation … Applied a geocentric coordinate system. Air friction is ignored. Covers fall and orbital motion due to Earth’s gravity. (However, the same can be applied to other celestial bodies.) Gravity Objects with mass exert … more
Buoyancy Experiment
The fluid in the beaker is water, and its density is assumed to be 1 g/mL. The volume of the object is assumed to be 100 mL. Buoyancy When we wear a life jacket, our bodies … more
Free Fall Experiment
This simulation allows you to measure speed as a function of fall height. Free fall movement All objects on Earth are affected by gravity. If there were no friction with air, the speed of any object … more
