物体碰撞时会发生什么
What happens when things collide
就物体碰撞时发生的能量变化提出问题并预测结果。
Ask questions and predict outcomes about the changes in energy that occur when objects collide
学习证据 / Evidence
- 根据物体的速度和大小预测碰撞的结果
- 解释碰撞过程中能量从一个物体传递到另一个物体
- 描述可观察到的变化：一个物体加速，另一个减速，并产生声音
- Predict the outcome of a collision based on the speeds and sizes of the objects
- Explain that energy transfers from one object to another during a collision
- Describe observable changes: one object speeds up, the other slows down, sound is produced
评估问题 / Assessment
如果{{name}}让两个球相对滚动，能预测它们碰撞时会发生什么，并解释能量在两者之间转移吗？
If {{name}} rolls two balls towards each other, can they predict what will happen when they hit and explain that energy transfers between them?
