Force Balanced and unbalanced
... That’s Right. As you may have noticed, although I may have balanced forces, I might still be moving. Notice that when the forces are balanced, the object might still be moving, but the objects are not accelerating, instead they have a constant velocity. Hence, once in motion – it’s always in motion ...
