partially elastic 問題 (momentum)

chiu1992

今日牙sir 講 elastic collision 分做 perfectly elastic 同 partially ealstic

而且 partially elastic 有energy loss during collision

但係 inelastic 唔係都有相同意思嗎??

究竟點分  幫幫手  唔該

piyopiyo

Inelastic collision---> all KE lost...
Partially elastic collision---> part of the KE lost
perfectly elastic collision---> no KE lost

Puppet

(perfectly/completely) elastic: no KE loss (KE is conserved)
Inelastic: KE is lost (KE is not conserved)
In particular, perfectly/completely inelastic: maxium KE loss

但係我牙sir  話 partially elastic 都有ke lost

咁究竟  partially elastic 同inelastic 有咩分別?

一個loss 晒, 一個未loss晒囉.

LOSS 曬好似係 completely inelastic
loss 唔曬 先係inelastic

有loss就是inelastic
loss係maxium就是inelastic內的completely inelastic
唔係"lost哂就是completely inelastic"

係的- -""


但係請問一下..... 究竟 partially elastic 同 inelastic有咩分別呢?

字眼ge分別而已...難道世界上所有字都應該不同意思嗎??[[tk_02]]   



















我估係咁
