= the (square of the velocity (m/s) * drag coefficient ) newtons
if terminal velocity is known (forces balanced , no further acceleration), drag coefficient can be found.
say terminal velocity(tv) = 70 m/s, acceleration due to gravity(g) = 9.8 m/s^2,
mass(m) = 80kg
m * g (force down) = tv^2 * drag coefficient (force up) at terminal velocity
then
m * g / tv^2 = drag coefficient
80 * 9.8/4 900 = 0.16
The upward force of air against a moving object is called lift. It occurs when the object's shape and angle of attack create a pressure difference between the top and bottom surfaces, generating an upward force that opposes gravity. This principle is fundamental in aerodynamics and is essential for the flight of aircraft.
force (newtons) = (air) velocity2 * drag coefficient
some (typical) drag coefficients:
family car = 0.45
motorcycle = 0.25
freefaller = 0.15
note: velocity is in metres per second

What is and upward force of air against a moving object?
The upward force of air against a moving object is called lift. It is generated due to the pressure difference between the top and bottom surfaces of the object, creating enough force to lift the object against gravity. This is essential for the flight of aircraft and other flying objects.
What if the upward force of an object is more than the downward force of an object?
If the upward force acting on an object is greater than the downward force (its weight or force of gravity), the object will experience a net upward force causing it to accelerate in the upward direction. This could lead to the object moving upwards, overcoming the force of gravity pulling it downward.
Is an upward moving object experiencing an upward force?
If the object is moving upwards with a constant velocity, there is only one arrow in the diagram, and it points straight down, due to gravity. If it has a force pulling upward on it, there are two arrows, one up, due to the force, and one down, again, due to gravity.
What is an downward force of air against a moving object?
An example of downward force of air against a moving object is drag. Drag is the resistance force exerted by air on an object moving through it in the opposite direction. It acts to slow down the object's motion by creating a counterforce against its movement.
What is the acceleration of an object moving upward?
The acceleration of an object moving upward is negative as it acts in the opposite direction of the object's motion. This acceleration is typically due to gravity pulling the object downward, causing it to decelerate as it moves against the force of gravity.
What is an upward force of air against a moving object?
air resistance
Is the upward force of air against a moving object?
air resistance
What is and upward force of air against a moving object?

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).
What if the upward force of an object is more than the downward force of an object?
If the upward force acting on an object is greater than the downward force (its weight or force of gravity), the object will experience a net upward force causing it to accelerate in the upward direction. This could lead to the object moving upwards, overcoming the force of gravity pulling it downward.

What force call against moving object?
Friction. Opposing Force
What is the acceleration of an object moving upward?
The acceleration of an object moving upward is negative as it acts in the opposite direction of the object's motion. This acceleration is typically due to gravity pulling the object downward, causing it to decelerate as it moves against the force of gravity.
Which force pushes against a moving object when it passes through water?
The force that pushes against a moving object as it passes through water is called drag. Drag is caused by the resistance of the water pushing against the object as it moves through it. This force can slow down the object's motion.
What is buoyancy Against what other force does it act?
Buoyancy is the upward force exerted by a fluid that opposes the weight of an object placed in the fluid. It acts against the force of gravity on the object, allowing objects to float or be suspended in a fluid.
When the buoyant force on a submerged object is more than the weight of the object?
The net force on the object is upward, so the object accelerates upward in the fluid.
