一架車brake既時候 kenetic energy 會change做d咩？
如果架車開頭一路用constant velocity, then brake,
佢decelerate 既energy會點change?

✔ 最佳答案
由 Kinetic energy 轉為 heat energy, 因為剎車時係由剎車碟同剎車皮產生摩擦而減慢車輪轉速。

動能kenetic energy變成聲能sound energy同熱能heat energy

in fact,theKE will not only change to heat energy,but also work done to the friction.Some KE may lost as sound energy also.

simple d 講
d kentic energy會在brake mechanism 因為friction between the brake material and drum/disc
change 左做heat energy
actually 整個decelaration應該計埋engine brake,transmission fiction,有冇上落斜,air resistance,tyre friction, etc.
