How can you tell if an object is accelerating?

If an object is changing its velocity -whether by a constant amount or a varying amount

Explanation:

then it is an accelerating object. And an object with a constant velocity is not accelerating.

the object can be accerleratting because the object supports it then later goes up for example a ball. if it supports that means its positive. if it has the weight like i mean by initially at rest. this means its negative. Hope this helps!
