Which of the following cases represents a uniformly accelerated motion?

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

A)1only
B)2only
C)1 and 2

b?

(1) only true for slope =0
(2) true for all value of constant slope

I think the answer should be "B"

頂,寫左C

可能"arm"呢...

如果題目有個 "may" 字我會選cccc~!

c 啊

slope 係0 係唔係constant

c 啊 [表情]
slope 係0 係唔係constant [表情]

一條斜線個slope都係constant喎~

會唔會有個ans

如果 "b" 有1.3倍
我會買

如果 "c" 有 500倍
我會小注...

呢D叫因才拖教

你係唔係照打個題目出黎?

唔通 slope=0 唔係 constant?
