You don't. There are at least 4 serious problems with the whole idea:
-- If force and speed could be converted, then you'd be able to calculate how many
miles per hour a turkey you need for Thanksgiving dinner, and you might get a
traffic ticket if you drove down a quiet residential street at too many pounds.
-- Force doesn't even produce a definite speed. A push of 40 pounds against a bicycle
produces more speed than a push of 40 pounds against a school bus.
-- And the longer you keep pushing with the same force, the higher the speed goes.
-- And an object that's moving keeps moving at the same speed forever with no force
on it at all.
Wind resistance can be calculated using the drag equation: drag force = 0.5 * drag coefficient * air density * velocity^2 * frontal area. The drag coefficient and frontal area of the object experiencing wind resistance need to be known in order to calculate the drag force.
Wind pressures exerted on a structure depend on the speed of the wind as well as the interaction between the air flow and the structure. Since wind is air in motion the pressures it can exert are related to its kinetic energy. If the full kinetic energy is transformed into pressure then the resulting increase is given by the expression q = ½ Ï V².
where q is the wind pressure, Ï is the mass density and V the velocity of the air. The mass density of the air 1.292kg/m3 at 0°C or 1.204kg/m3 at 20°C.

FD = 1/2 · ρ · v2· A · CD
Where,
FD is the drag force
CD is the drag coefficient,
ρ is the density of air
A is the cross-sectional area of the ball (a regulation Baseball has a circumference between 9 and 9.25 inches), and v is the velocity of the ball.
The drag coefficient is a function of things like surface roughness, ball speed, and spin, varying between 0.2 and 0.5 for speeds commonly occuring during game play, but if you'd like to ballpark it (pardon the pun), 0.3 is a good number to use.

Drag resistance is typically tested in a wind tunnel by subjecting the object to airflow at varying speeds. The force required to push the object through the air is measured, and this data is used to calculate the drag coefficient, which quantifies the drag resistance of the object. Advanced computational fluid dynamics software can also be used to simulate airflow around the object and calculate drag resistance.
When wind pushes against a surface, it can create a force known as wind resistance or drag. This force increases with the wind speed and the surface area of the object being pushed. The shape and orientation of the object can also affect the amount of wind resistance it experiences.
To calculate an unknown resistance, you can use Ohm's Law, which states that resistance (R) equals voltage (V) divided by current (I). You can measure the voltage across the unknown resistance using a multimeter and the current flowing through it using an ammeter. Then, you can divide the voltage by the current to calculate the resistance.
Wind resistance is typically greater near the ground due to surface friction and obstacles that disrupt airflow. As you move higher in the air, wind resistance decreases because the air is less turbulent and obstacles are less frequent, allowing for smoother flow.
Yes, the shape of a toy car can affect wind resistance. A sleek and aerodynamic shape will reduce wind resistance, allowing the car to move faster and more efficiently. In contrast, a boxy or irregular shape will create more drag and slow down the car.
Wind resistance is a specific example of air resistance. Wind resistance would be a resistance to motion cause by a wind, for example when you try walking forward on a very windy day it is hard, that force preventing you from walking is wind resistance.
Wind resistance may occur anywhere where there is something i the way of the wind. Whether it may be a person, a car, or a mountain, they all resist the wind.
Resistance is resistance , no matter if it is contact resistance or any other resistance. And formula is R = V / I.

less wind resistance for your hairy legs. Shave and you will have the same affect.
To calculate the resistance of a single core wire, you will need to know the resistivity of the material the wire is made of, the length of the wire, and the cross-sectional area of the wire. You can use the formula: Resistance = resistivity * (length / cross-sectional area). Plug in the values for the resistivity, length, and cross-sectional area to find the resistance of the 70mm^2 single core wire.
All jackets will protect you equally, for the most part, from the wind.
The resistance force multiplied by the resistance distance.
Wind resistance.
it is the amount of wind resistance that something creates.
Air resistance can reduce the speed of a bouncing ball upon impact with the ground, resulting in a lower bounce height. The drag force from air resistance opposes the upward motion of the ball, thereby decreasing the energy transferred during the bounce. Overall, greater air resistance can lead to a shorter and less energetic bounce.
Wind resistance (actually, Air Resistance) works against a car- it has to push air out of the way. Cars that are "streamlined" are designed so they slip through the air more easily than those that are not.
