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.
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.
the vertical accelaration in case of a projectile is 'g'.
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.
yes when ignoring air resistance
Ignoring air resistance, it would be a parabola.
Well ofcourse it will be air resistance
