速度与能量
Speed and energy
运用证据构建一个解释，说明物体运动的速度与该物体所具有的能量之间的关系。
Use evidence to construct an explanation relating the speed of an object to the energy of that object
学习证据 / Evidence
- 解释运动中的物体具有能量，且运动速度越快，能量越大。
- 从观察中提供证据（例如，速度更快的球会造成更大的破坏或更明显的运动）。
- 恰当使用“动能”或“运动能量”等术语。
- Explain that a moving object has energy, and the faster it moves the more energy it has
- Provide evidence from observations (e.g. faster ball causes more damage/movement)
- Use the term 'kinetic energy' or 'energy of motion' appropriately
评估问题 / Assessment
{{name}}能不能用“物体运动得越快，能量就越大”的道理，解释为什么快速移动的球比慢速移动的球能撞倒更多的球瓶？
Can {{name}} explain why a fast-moving ball knocks down more skittles than a slow one, using the idea that faster things have more energy?
