Phy MC
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
2 Only
1)一定係錯
除左slope=0之外,有slope就a-t graph就已經唔係uniformly accelerated
用返"AND"既logic, 當有一樣野錯既時候,就唔可以當佢岩\
所以一定係2 only
CE問既係"In all cases unless specified"
