337Acc. = Change in velocity/ time.
Velocity includes both magnitude and direction as it is a vector quantity. So magnitude can be zero but direction can change. So, I think, the answer is yes.
A top, which is spinning but not moving away from its place can be a good example. It is a stationary object rotating in its place.
N.B.: All the above statements are valid for point objects. The top is not a point. All the points of the top have some velocity, except for the points lying on the axis of the top.
Thanx...
Hope it helps...
Debal Roy you had to think that the top has angular velocity from which we can get a value of linear velocity.but that is not question.
the question is -
is there any possibility of zero velocity and non-zero acceleration in case of linear motion? Upvote·0· Reply ·2013-03-13 01:30:14- Sayan Sinha The top is not a point. All the points of the top have some angular velocity, except for the points lying on the axis of the top. I need to think about the case in linear motion and I will try to answer in some time.
