Question

In high school physics problems, does 0 count as "constant speed?"

Answer 1

0 speed means object is at rest. In my opinion, it is also at rest in high school physics. So, no.

Answer 2

0 acceleration can be counted constant speed

Answer 3

If it is constantly zero, then it is constant. Of course in mathemathical equations the terms with the speed in it disappear because it is zero. So it doesn't matter if you take it "at rest" or "at constant speed with 0 meters per second". They both mean the same thing.

Answer 4

Zero what? This is the reason why all professor /teacher say to use units. There is a huge difference between a= 0 m/s^2 (ie you are at constant speed with zero acceleration) or v=0 m/s ( you are not moving). Yes, v=0 m/s can be considered a constant speed. However, there is no physical meaning when you say moving at constant speed at 0 m/s. Physically that means you are at rest! Check you units, what quanity is zero?

Answer 5

If there is no acceleration than the speed does not change is therefore constant. Is does not matter if the speed is 5 or 0 it is still constant despite of it´s magnitude.

Answer 6

as your question states whether zero counts as constant speed the answer would be no ! but whereas like the above people have stated if your talking about zero acceleration then its definetely constant speed !

Answer 7

Speed can be stated as a function of time and in this case we have S(t)=0. Definitely it is a constant function and hence, a constant speed.
I think your question is whether we have defined the speed zero or not and the answer is Yes, we have defined; so we can say its speed is constant.
