Newton's 2nd Law of Motion states that F = m * a, where F = the net force acting on an object [N]; m = the mass of the object [kg]; and a = acceleration [m/s2] . If the motion is linear, then we can consider scalar operations on F and a. If the force is a vector, then a has to be a vector too.
============================
Picking up a glass of beer from the table.
Force of gravity . . . down.
Force of arm muscle . . . upward.
Forces are unequal. Upward force is greater than downward force.
Glass accelerates upward, toward mouth.
You're talking about "unbalanced forces". But the change in the object's motion
is not in the direction of the larger force. It's in the direction of the vector sum of
all the forces, which is not necesssarily the direction of any single one of them.
If the sum of all forces acting on one object is not exactly zero, the forces are said to be unbalanced. In that case, the object will accelerate.
an unbalenced net force
Long Q'n. Short Answer is Physics.
If there are two or more unequal forces acting on an object then the object will be acting on the forces. ^_^
Because it describes the aspects,motion,behaviour of nature regarding forces acting on objects and their reactions under the behaviour of those forces
for every action there is a reaction so this is the force.
All objects on earth have the force of Gravity acting on them.
There are many forces acting on a body. But, the moves because of the net force acting on it. So, we can say that the body accelerates because of net force acting on it only.

Unequal
If the forces acting on an object are equal there is no motion (5N->O<-5N). If the forces are unequal there is movement (7N-->O<-5N).
If there are two or more unequal forces acting on an object then the object will be acting on the forces. ^_^

All objects accelerate if the forces acting on them are not balanced.
Objects will accelerate if there is a net force acting on them.
