The forces acting on a stationary object are:

∙ 12y agoIn that case, the object's velocity won't change.
By definition, every force acting on the object affects its velocity.Newton's second law states that the acceleration of an object (the rate of change of velocity with time) is equal to the net force on the object divided by the object's mass. Force is a vector, so if you have several forces acting on the object you must take their vector sum. Only if all the forces acting on the object sum up to zero will the object not accelerate. In that case it will remain stationary if it was already stationary, or continue to move in the same speed and in the same direction as before.
c is correct.
A very simple answer for an unspecific question: Force = Mass x Acceleration If you increase the force acting on an object you will also increase that objects acceleration (If the force on a stationary object is enough to overcome friction or if the force is in the same direction that an object is already moving, etc.).
weight, The weight of an object is the force of gravity acting on it.
It remains stationary
No. An object that has no net force on it will simply not be accelerating. It can be in motion, but it can not have any change in its velocity.
In that case, the object's velocity won't change.
If an object is stationary on a surface then the forces acting on it are the Gravitational force and the Normal force(the force of the surface pushing back against the object). Technically you could be pulling(or pushing) that object from opposite directions with equal forces and it would remain stationary. The important thing to understand is that a stationary object remains stationary so long as the net forces applied to it equal zero.
The forces acting on a stationary object are balanced. If you were to add up all the forces (taking the directions into account, you would get a total of 0. There are always forces acting on a object, such as gravity, so you cannot say that there are no forces acting on it. You can say that the forces are balanced.

c. Free fall
c is correct.
Absolutely. The key is to realize that a net force of zero on an object means only that it is not accelerating. This means that an object feeling zero net force can either be stationary or moving at constant speed in a straight line.

Normal force is the force of a surface acting on an object( the normal force is perpendicular to the plane of contact). This force is directly related to the force of gravity, as the third law of newton state that when a force is applied to an object it will react with an equal force in the opposite direction. So when an object is placed on a surface, the force of gravity is acting on it (pulling it down), but the is object remain in place due to the normal force (which is pulling up on the object). In addition, a change to the force of gravity will result in the same change to the force of normal, to allow an object to remain stationary.
