Not "affect"; the word is "effect" in this case. Yes, air resistance has an effect on projectiles.

The main forces acting on a projectile are gravity, and air resistance.


Not if you can ignore air resistance, it doesn't.


Gravitational force only. 2. Air resistance has effect also.


no it dosen't due to the force calculated and air resistance is negleted


Air resistance acts against the motion of the object. Whatever range you get when assuming no air resistance is too large.



Gravity is pulling the projectile down steadily; the further it climbs, the more resistance it's recieving, it begins to slow down, as with any projectile.



Ignoring air resistance, it would be a parabola.


-- In the absence of air resistance, the object's diameter has no effect at all on the projectile motion. -- In the presence of air resistance, one has to know everything about the object AND the air in order to have a prayer of calculating the effect.


Well ofcourse it will be air resistance



Air resistance decreases the distance to the projectile's landing site, compared to the distance you calculate when you assume no air resistance. The limiting case is: An artificial satellite encounters no air resistance, and does not land.


Fluid density, relative velocity, and object shape affect air resistance.


Air resistance is proportional to the cube of speed.




It is if air resistance is ignored. So the answer is: "Yes, but as an approximation."


If there wouldn't be air resistance and gravity is the only thing that is effecting the projectile, the projectile will start to fall but it horizontal velocity will remain the same. So it would slow down, it would only change height.


If you can ignore the effects of air resistance, the horizontal component of projectile velocity doesn't change at all.


Wind, elevation, trajectory, projectile weight, projectile configuration, barrel length, barrel rifling, friction or resistance in the barrel, force (charge) behind the projectile. There are other enviornental elements that can affect range as well.


Assuming negligible air resistance, the acceleration of a projectile near the Earth's surface is always the gravitational 9.81 m/sec/sec downwards, regardless of where in the trajectory the projectile is.


Some of the factors that determine the movements of a projectile include: air resistance, force of gravity, initial launch velocity, the angle a projectile was launched at, and the objects initial elevation.


Air resistance slows you down which is why ski racers wear tight suits to minimize air resistance.


A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
