Can an object have a exkjx* dtt(wpl2+y:9 varying speed if its velocity is constant? If yes, give exnf 2v* k9qqmag8o b,g/aqq/go, 2*9kvnf g 8mbamples.
参考答案:
By
definition, if an object has a constant velocity, then both the object's speed
and its direction of motion are constant.
Therefore the object CANNOT have a varying speed if its velocity is
constant.
