A particle is travelling with a constant speed. This means
(a) its position remains constant as time passes|
(b) it covers equal distances in equal time intervals
(c)its acceleration is zero
(d) it does not change its direction of motion
(a) its position remains constant as time passes|
(b) it covers equal distances in equal time intervals
(c)its acceleration is zero
(d) it does not change its direction of motion
-
a) no, because it is moving
b) yes, because constant speed
c) no, there must be some acceleration because particle can change its direction of motion.
d) no, it may change
b) yes, because constant speed
c) no, there must be some acceleration because particle can change its direction of motion.
d) no, it may change
-
(b) it covers equal distances in equal time intervals.
if velocity is constant,even choices (c)&(d) will also be correct.
