Webتعرف الطاقة الحركية (بالإنجليزية: Kinetic energy) على أنها نوع من أنواع الطاقة التي يكتسبها الجسم مع الحركة بعد التأثير عليه بقوة معينة، ويختلف مقدار الطاقة الحركية للجسم باختلاف مقدار القوة المُطبّقة عليه، وباختلاف كتلة ... WebThe kinetic energy of the emitted electrons depends on the frequency of the radiation, not on its intensity; for a given metal, there is a threshold frequency below which no electrons are emitted. Furthermore, emission takes place as soon as the light shines on the surface; there is no detectable delay.
