合唔合格看呢題啦 [表情]

一題咁重要...

聽講 Physic 今日超難

引用第14樓智者於2007-01-11 15:45發表的“”:
你係唔係照打個題目出黎?
唔通 slope=0 唔係 constant? [表情]

acc-time slope=0 係constant　
ONLY = 0 先 "arm"

但問題係現在式
應該指　ＡＬＬ　ＣＡＳＥ

所以我估Ｂ
如果題目用個"may"字先似Ｃ

我都係估估下咋

都有機ｇｅ．．．．乙組仔都可以和車仔，有咩唔可以丫．

我係totally copy 條 question

29    Which of the following cases represents a uniformly accelerated motion?
(1)    A straight line with constant slope in a displacement-time graph.
(2)      A straight line with constant slope in a velocity-time graph.
(3)    A straight line with constant slope in an acceleration-time graph.
A.    (2) only                B.    (1) and (2) only
C.    (2) and (3) only        D.    (1), (2) and (3)

原本條題目．．． ４個ｃｈｏｉｃｅ先正常．

why u know the question

(1)   A straight line with constant slope in a displacement-time graph.
(2)     A straight line with constant slope in a velocity-time graph.

C.   (2) and (3) only     D.   (1), (2) and (3)

其實唔係應該剩係得2咋咩...


1一定唔啱嫁啦...如果uniform accelerate...應該係curve向上...

3可能啱可能唔啱....
因為如果佢條slope唔等如0.......就係increasing acceleration....
但係如果佢條slope等如0...就係uniformly accelerate....

但如果答呢題...我會要求一定啱的答案...所以我會choose A(2)only


原來小弟的愚見同ballfull一樣:p~~咁不講咁多了~
