Calculate drag coefficient of freefaller (prior to chute opening)
>
(constant) force down (in newtons) due to gravity = mass * acceleration due to gravity, say 80 * 10 = 800 newtons.
>
The up force (newtons) = velocity2 * drag coefficient
>
At terminal velocity (where up and down forces balance) the up force = 800 newtons, say terminal velocity = 70 metres / second
>
800 = 4900 * drag coefficient
>
Drag coefficient = 800 / 4900
>
Drag coefficient = 0.163
What else can I help you with?
What do you call things that that have little air resistance?
aerodynamic - you may want to check the spelling.
How are air resistance and friction alike?
Air resistance is a type of fluid friction (along with water resistance) and is therefore is a type of friction.
Non example of air resistance?
aeroplane.......because the horizontal force only got thrust force and drag force
What are facts about air resistance?
What type of friction is air resistance?fluid friction. Air resistance is fluid friction. Air resistance occurs between the surface of a falling object and the air that surrounds it. Rolling friction occurs when a rounded surface moves over a solid and sliding friction occurs when a solid moves over another solid. Static friction occurs when a solid touches another solid but there is no movement.What two factors affect air resistance?size and shape. Size and shape are the two factors that affect air resistance. Air resistance works with surface area, so the more surface area, the more air resistance. Think about when you drop two pieces of paper: one crumpled and one flat. The crumpled one falls faster because there is less air resistance acting on the paper.
Is air resistance a contact or non contact force?
Air resistance is a contact force because you are in contact with the air in order to apply that force.
Air resistance is an example of?
Air resistance is an example of a type of frictional force acting against an object's motion as it moves through the air. It occurs when the object comes into contact with air molecules, causing a deceleration in its movement.
What is a good example of air resistance?
A good example of air resistance is when a skydiver jumps out of a plane and feels the force of the air pushing against their body as they fall. This force slows down their descent and creates drag.
What is a example of fluid friction?
An example of fluid friction is the air resistance felt by an airplane.
What is an example of air friction?
An example of air friction is when an object moving through the air experiences resistance due to the interaction between its surface and the air molecules. This resistance slows down the object's motion, such as when a skydiver experiences air resistance while falling through the atmosphere.
What example of air resistance force?
An example of air resistance force is when a skydiver jumps out of a plane and experiences the force pushing against them as they fall through the air. This force acts in the opposite direction to the skydiver's motion and increases as their speed increases.
What is wind restance?
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.
What is an example of air resistance force?
An example of air resistance force is when a skydiver jumps out of a plane and experiences the force of air pushing against their body as they fall through the atmosphere. This force increases with the speed of the skydiver and can impact their descent speed and trajectory.
What force is an example of a friction?
You walk and that is the example of friction
What is an example of internal resistance?
Someone on a bike and the air in the tyres being displaced outwards.
Does air temperature affect air resistance?
There are two factors that influence air resistance with temperature. Air density decreases with temperature so that the force needed to push the air out of the way is decreased, thereby decreasing resistance. Conversely, air viscosity increases with temperature (unlike oil for example where viscosity decreases with temperature) so that the drag increases. Under normal conditions, the density change of air has the greatest effect and air resistance decreases at higher temperatures.
What occurs when there is no air resistance?
-- "free fall" -- absence of terminal velocity
How does are resistance effect speed?
Resistance can decrease speed by slowing down the movement of an object. In the case of air resistance, for example, the force of air pushing against an object moving through it can reduce speed. Increased resistance requires more energy to overcome, which can lead to a slower speed.
