Net force of an object?

Question

What is the net force acting on a 25-N freely falling object? What is the net force when the object encounters 15 Nof air resistence? When it falls fast enough to encounter 25 N of air resistence?

Answer 1

A force only exists when a moving mass is hindered by another mass. Hence in the absence of air the moving mass experiences no force exept the interaction between the mass and the gravity field.
When ever a force is force is born and equal and opposite force occurs(a reaction force).
When a mass is in free fall it does so because Gravity power is pushing down towards the mass of the earth.
As the mass falls it experiences a continulaly increasing acceleration and a shortening of time per osciliatory displacement causing an increasing velocity as it falls towards the Earth. When it collide s with the earth it experiences a force plus a reactive force.
The mass of a 25 newton weight of an object is 2.5 pounds at the surface of the earth. It is the power of gravity that acts on the mass to make it move.
