顶部的势能(Potential Energy)。 当球下降到一半高度时,动能(Kinetic Energy)是多少?(提示:运用机械能守恒定律) 下图展示了一个理想的单摆(Pendulum)摆动过程: 位置A(最高点) → 位置B(最低点) → 回到位置C O O(B点,最低点) \ / \ / \ / O 请说明单摆在位置A(最高点)与最低点B之间如何体现机械能
This lesson describes the difference between potential and kinetic energy of a pendulum, and it explains how to calculate each.
Energy is the capacity to do work. ... The unit of energy is J (Joule) which is also kg m2/s2 (kilogram meter squared per second squared)
At which point during its swing does the pendulum have the maximum potential energy and the minimum kinetic energy? At the lowest point in its swing. At the highest point in its swing. Correct Answer A. At the highest point in its swing. Explanation The pendulum has maximum potential ...
