This simulation models the process of two sinking pieces of clay with equal densities and masses but different shapes. Here’s a question: When describing ship sizes, the term “displacement (tonnage)” is often used. Why?
LAB
This simulation models a transverse wave traveling toward the right with a speed of V cm/s. Students can change the amplitude, wavelength, and period of the wave to observe their effects on the waveform.
此程式模擬一以波速 V (公分/秒)向右行進的橫波。學生可調控波的振幅,波長,與周期觀看此橫波隨時間波形的變化。

This simulation explores the effect of frictional force in a scenario where two objects stacked on top of each other are subjected to a an external force. Can you figure out the relationship between Ma and uab so that the present does not slide off the sled?
LAB
This simulation models the process of putting an orange block of mass M (g) and volume V (cm^3) into a blue solution with density rhoS (g/cm^3) in order to investigate the concept of buoyancy.
此程式模擬將一個重量為 M 公克,體積為 V 立方公分的橘色方塊慢慢浸入密度為 rhoS (公克/立方公分)的藍色溶液中的過程,以探討浮力概念。
LAB
This simulation explores motion at a constant velocity and motion during free fall.
這是一個運用等速度運動與自由落體的概念設計的合作問題解決題目。
LAB
Two objects with different masses slide down a ramp. Which will slide down first?
此程式模擬兩不同質量的物體從斜面下滑的運動過程,你猜誰會先滑下去呢?
LAB
This simulation explores the horizontal and vertical components of an object during projectile motion. A crack shot aims his gun at an apple which will begin to free fall when he pulls the trigger. How can he make sure that his bullet will hit the apple?
LAB
This program simulates the dynamics of a pyrotechnic star as it is launched into the sky and explodes into two parts at the highest point of its trajectory.
此程式模擬一質量為600公克的煙火彈被射入天空,當它升到最高點時爆炸成兩塊煙火碎片後落下的運動過程。

A giant runs at velocity V in the rain from underneath roof m to roof n. His velocity (V) and the density of the rainfall (rho) can be changed.
此程式模擬在雨中以不同速度 V 奔跑的巨人,從屋簷 m 跑至屋簷 n 過程中淋雨的狀況。可調參數為奔跑速度(V)與降雨密度(rho)。
