10/12 AP Physics C
Today in AP Physics C, students performed an experiment in order to determine what properties of objects affect how fast they roll down a ramp. They rolled multiple objects, including batteries, rolls of tape, and even a bowling ball! Students predicted the final speed of the objects at the bottom of the ramp using conservation of energy. Then they measured the final speed using a stopwatch, a meter stick, and concepts learned in the kinematics unit. In their lab reports, students will compare their predicted speeds with the speeds they measured in the experiment.
在今天大學物理先修課程中，學生們進行了一項實驗，為確定物體的屬性不同會影響物體滑下坡道的速度。 他們實驗滾動了多個不同物體，包括電池、膠帶捲，甚至還有一顆保齡球！ 學生利用能量守恆定律，來預測物體滾動到坡道底部的最終速度。 然後他們使用碼錶，量尺和運動學單元學到的概念來測量最終速度。 最後他們將在實驗報告中，比較預測速度和實驗測量的速度二者的差異。
