Level 1: Knowing and Understanding
Уровень 1: Знание и понимание
Match the descriptions to the correct energy type:
Transformation Equations
Уравнения трансформации
How is the energy transferred in these scenarios?
Interactive: The Pendulum
Визуализация закона сохранения (Drag the slider to swing!)
(В замкнутой системе энергия не создается и не исчезает. Она только преобразуется.)
Level 2: Applying & Analyzing
Уровень 2: Применение и анализ
The Half-Pipe (Скейт-рампа)
A skateboarder is standing at the very top edge of a U-shaped ramp. At this highest point, they have 2500 J of GPE. Assume no friction.
The Spring-Loaded Dart (Дротик на пружине)
A toy dart gun uses a compressed spring to launch a plastic dart. When fully compressed, the spring stores 12 J of EPE.
CLIL Sentence Starter:
"According to the Law of Conservation of Energy (Согласно закону сохранения энергии), the total energy remains constant, which means all 12 J of EPE is entirely converted into 12 J of KE."
Level 3: Evaluating & Creating
Уровень 3: Оценка и создание
The Trampoline Bounce (Прыжок на батуте)
Analyze the physics of a gymnast jumping. For each stage, identify the dominant form of mechanical energy.
Lesson Completed!
You have mastered the Conservation of Mechanical Energy.
- Energy cannot be created or destroyed.
- Ek + Ep = Constant in a closed system.
- When height decreases, velocity increases to compensate.
