force down f=ma
air restance force is dependant on velocity and aerodynamics
say 100kg falling , terminal velocity = 70m/s
f=ma = 100 *10 = 1000n
at terminal velocity forces equal
air resistance 1000n = v^2* resistance figure for this body (r)
r = 1000/v^2
r = 1000/4900
r = 0.204 this figure can be used to calculate air resistance at different speeds

Is a net force being applied to a object when its moving downward with a constant acceleration of 9.80?
Yes, of course. If it is accelerating, it follows directly from Newton's Second Law that there is a net force acting on the object.
When an object is falling at terminal velocity what is the net force acting on the object?
Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
What hapPens to the net force of the object if it is at rest?
In that case, the net force on the object is zero.
What Combination of all of the force acting on an object?
This would be known as the net-force.
A simple net force definition?
A net force is a measure of the force being exerted on an object; zero net force means an object is at rest or moving at a constant speed.Definition of net force:The net force on an object is the vector sum of all individual forces acting on it.
What is the net force that acts on a 10- freely falling object?
Ten newtons downward, by definition.

Zero. "Terminal velocity" means that the object is no longer accelerating; the downward force of gravity and the upward force of resistance are in balance.
How is it possible for an object to sink even though a buoyant force is pushing on it?
An object will float if it is less dense than the liquid in which it is placed; if it is denser, it will sink. In terms of forces, if the force of gravity (downward) is greater than the buoyant force (upward), then of course the net force will be downward, and the object will sink.
What is the upward force on a moving object with a lift at a rate of 17m per s?
If the object is moving at a constant speed, the net force on it is 0. So the upward force would have to be equal to the downward force (namely the weight of the object).
The downward force acting on an object in free fall is the force of what?
The downward force acting on an object in free fall is Gravity.
Why does a egg gain speed on the way down?
Any falling object, or object that rolls downwards, can gain speed. This can easily be explained by Newton's Third Law: acceleration = force / mass. Force refers to the net force. So, as long as there is a net force downward, the object will continue accelerating. Only when the upwards forces (basically, friction) become as strong as the downward force of gravity will the object start accelerating. In that case, the object is said to have achieved "terminal velocity".
What is the buoyant force on the object theat weighs 20n and it displayes a volume of water that weighs 15n?
The buoyant force is the weight of the displaced water. That's 15n, and it points upward. That upward force combines with the downward 20n due to gravity. The net force on the object is 5n downward.
Can something move 1 direction and have net force in the other direction?
Yes. What the net force does is affect acceleration. For example, when you throw an object up, once it is in the air the net force on it is downward - so of course it accelerates downward. But due to the fact that it was initially moving upward, it will continue moving upward - at least for a while.
If a non zero net force acts on an object what does the object do?
-- When the net force on an object is not zero, the object undergoes accelerated motion.-- The magnitude of the acceleration is the ratio of the net force to the object's mass.-- The direction of the acceleration is the same as the direction of the net force.
Is gravitational force equal to the weight of the fluid displaced by an object?
No. Gravitational force is directed DOWNward. The weight of the displaced fluid is another force, directed UPward. If they happen to be equal, then the net force on the object is zero and it floats. But they don't have to be equal.
What is net force on an object at rest?
The net force on an object at rest is 0.
