What are two forces that are not equal in size?
friction Also we can mention the forces acting on a sinking body in a liquid. The weight is more than the buoyant force
What two forces that are not equal in size are?

When a truck pulls a trailer and truck accelerate forward even though the action and reaction forces are the same size but are in opposite directions why don't these forces balance each other?
Because the forces are acting on two different objects
What happens when two forces of different magnitude and opposite direction act on a abject?
The difference in size of the forces is calculated, that will then be the force acting in the direction of the larger force. Force1= 3 N <--- Force2 = 10 N ----------> Resultant Force = 7 N ------->
What is it when you add two forces acting on an object?
Two forces acting in the same direction cause the body to speed up (accelerate) if the forces are acting in opposite directions, subtract one from the other. The difference is the net force on the body and will be the direction in which it accelerates. Obviously, if they're the same size and opposite in direction, providing the body is rigid (it doesn't deform, in other words), the stat of motion of the body will stay the same (either at rest or moving at a steady speed in a straight line).
Forces that are equal in size but opposite in direction are called unbalanced forces?
False forces that are equal in size but opposite in direction are called balanced forces. Unbalanced forces acting on an object cause the object to accelerate.

What must be true about the forces acting on an object if the motion of the object does not changes?
The forces must be balanced; the forces must be equal in size and opposite in direction. (Net force must equal zero).
What are unbalanced forces and what?
Balanced forces describes when all forces on an object are equal. Unbalanced forces describes when the forces on an object are unequal, resulting in movement. Forces are balanced when the vector sum of all the forces acting on the object is zero, at which point the object will be at rest or be in motion with constant velocity. Forces are unbalanced when the vector sum of all the forces acting on the object is greater or less than zero, at which point the object will accelerate by either starting motion from rest, or changing its motion if it is already in motion, for example, by changing direction or speed.

these foces do not balance because both of the forces arent acting upon the same object
What is the net force equation?
It means the same as the sum of all the forces acting on an object. Note that since forces are vectors, they have to be added as such. For example, an book resting on a table has gravity pulling it down; on the other hand, the table is pushing the book upwards (by Newton's Third Law; since the book pushes down on the table). Adding all the forces together, you get a zero force - which must be so, for the object to remain at rest.
