Acceleration is a vector, meaning each acceleration has both magnitude and direction. The resultant of vectors is basically the net acceleration on the object expressed as a single vector. For example, if there are two vectors each with a magnitude of 2 meters/(seconds squared) acting on an object and these vectors were placed on the x and y axes then you could represent this system of 2 vectors 90 degrees apart each with a magnitude of two meters/(seconds squared) as one vector of 45 degrees with a magnitude of 2 times the square root of 2 meters/(seconds squared).

Yes, a cart loaded with groceries has more inertia because it has more mass than the empty cart. The inertia of any object is determined by the amount of its mass.

No it is not bad, as some ladies have a heavy period for one month and then a light one or they may have two heavy periods and then one light one also.

Not exactly. Velocity is the speed and direction of an object's motion.
If either speed or direction changes, then the change is the object's 'acceleration'.
