Speed and energy
速度与能量
Description
Use evidence to construct an explanation relating the speed of an object to the energy of that object
Mastery Evidence
- 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
Assessment Prompt
Can your child explain why a fast-moving ball knocks down more skittles than a slow one, using the idea that faster things have more energy?
