= 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
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
The upward force of a moving object is known as "lift".
air resistance
i think it's air resistance.
its called air resistance. I'm sure.
The force of air resistance is.
The upward force is drag.
The greater the pressure against the bottom of a submerged object produces an upward buoyant 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.
The upward force exerted on an object in a fluid is buoyancy.
The upward force exerted by a liquid on a submerged object (or even on a floating object) is called buoyancy.
The upward force is drag.
air resistance
air resistance
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 greater the pressure against the bottom of a submerged object produces an upward buoyant 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.
Friction. Opposing Force
The upward force exerted on an object in a fluid is buoyancy.
The net force on the object is upward, so the object accelerates upward in the fluid.
the magnitude is 43.3 and the direction is upward.
The upward force exerted by a liquid on a submerged object (or even on a floating object) is called buoyancy.
buoyancy is the upward force that water exerts on an object. :)
