And what that means is if the velocity is constant, then the acceleration is essentially equal to zero. And so that implies that the thumb of the forces acting on that object along the x axis is equal to zero. Now, with that in mind, let's actually see what the left side of this equation is. So let's take a look at all the forces acting on the object. So this is the Positive Force and these are the two Negative Forces. So let's use red for that positive force.
