當一架車減速時對摩擦力所作的功是否所有對摩擦力所作的功同一時間轉化為地面和摩擦力的"耐"能??
我可唔可以直接寫動能轉為車的地面的"耐能"???

✔ 最佳答案
What do mean by "摩擦力的"耐"能"??? Friction is a force...what is the "耐能" of a force?DUring braking, the friction between the tyres and the ground produces heat (熱能), which is being absorbed by the tyres as "internal energy"(內能). This is the reason why the tyres of a vehicle get hot after braking.

Friction is not a internal energy~
