(Forces in newtons)
The (constant) force down on a freefalling body is : mass (kg) * acceleration due to gravity ((m/s)/s) .
The force of air resistance up is : velocity2 * drag coefficient .
>
The net force is the difference between the two .
>
Acceleration at any given velocity is given by net force / mass .
>
Terminal velocity is where the down and upforces balance .
>
>
Drag coefficient can be calculated if terminal velocity, mass and acceleration due to gravity (g) are known.
Example:
Terminal velocity = 70 m/s, Mass = 70 kg, g = 9.82 (m/s)/s
Then >
force down = 70 * 9.82 = 687.4 newtons
forces are equal at terminal velocity so air resistance = 687.4 newtons @ 70 m/s
So >
687.4 = v2 * drag coefficient
So >
drag coefficient = 687.4 / v2 = 0.14 (approx) .

What factors affects balloon rocket?
The factors that affect a balloon rocket include the size of the balloon, the amount of air inside the balloon, the length and material of the string, and the smoothness of the surface the rocket is traveling on. Additionally, external factors like air resistance and wind can also influence the rocket's speed and direction.
What three factors affect the amount of air resistance acting on a object?
The factors that affect the amount of air resistance acting on an object are the speed of the object, the surface area exposed to the air, and the shape of the object. A faster object experiences more air resistance than a slower one, a larger surface area increases air resistance, and a streamlined shape reduces air resistance.
What three factors affect the amount of air esistance on an object?
The three factors that affect the amount of air resistance on an object are the object's speed (faster speed leads to higher air resistance), the object's size and shape (larger or less streamlined shapes experience higher air resistance), and the air density (higher air density increases air resistance).
Is this question true or false when there is less gravity there is less gas?
False. The presence of gravity does not directly affect the amount of gas in an atmosphere. Factors such as temperature, pressure, and chemical reactions play a larger role in determining the composition and amount of gas in a given atmosphere.
What two factors affect the amount of gravity?
Gravity is affected by the masses of the objects, and the distance between them (really the distance between their centers). Greater mass increases the force of gravity. Greater distance decreases the force of gravity.
What 3 factors affect the amount of air resistance on an object?
Speed, shape and frontal cross-section. Viscosity, texture, friction, gravity, velocity, size, and shape can all affect air resistance.

What factors affect the amount of gravity between two celestial objects in space?
Not only in space - gravity is universal. The force of gravity is affected by the distance, and by the masses involved.
How do mass of the objects affect the force of gravity?
The greater the mass, the stronger the gravity, but the distance does not affect the amount of gravity.

What are the factors that affect the resistance of a conductor?
The factors that affect the resistance of a conductor are the material it is made of, the length of the conductor, the cross-sectional area of the conductor, and the temperature of the conductor. Materials with high resistivity, longer lengths, smaller cross-sectional areas, and higher temperatures will have higher resistance.
