What do you get when you subtract the force of air resistance?
No it is a non conservative force
It requires a force to propel an object through air, because of the air resistance. Normally, if there were no air resistance and the object were being propelled on the le…vel with no friction, a constant force would accelerate the object steadily. However, it would require a steady force to propel the object through air even without acceleration. And the faster it went the more resistance it would meet.
Air resistance is a contact force because you are in contact with the air in order to apply that force.
it is contact force
Compare the force of air resistance and the force of gravity on an object falling at its terminal velocity?
when an object is falling down towards the earth , it's pulled downward towards the earth the force of gravity . however , a friction like the force of air resistance opposes …the motion of objects to fall with different acceleration , speed and direction . if the object is falling down the air resistance acts upward.
Air resistance can be roughly translated as drag or friction of the wind causing something to slow down.
Yes resistance would be a push force.
In aeronautical parlance, it is called drag.
Gravity is stronger. If gravity was not stronger air would make us float away. Air is trying to make things go up and gravity is making things go down.
First of all, gravity is not a force, it is an acceleration. What you mean is the force of weight, which is the acceleration of gravity multiplied by mass (all forces are vect…ors, and gravity is not a vector.) When air resistance is subtracted from weight, you have the net force on a falling object (assuming those are the only forces acting on it.)
Air resistance is a force that gets larger as an object moves faster. Consider Einstein's equation E = mv2 and Newton that "for every reaction there must me an equal and oppo…site reaction." The latter is the law of Conservation of Energy. Resistance is a force, E, opposing another force in the opposite direction. V in the equation is velocity or speed. The opposing force in this case is the resistance of air and the reason why objects do not move forever except in space where there is no air.
= 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
