thanks guys ! :)

or net force is not same as force ??

if the plane need move it need force right ? so why the plane can move with a constant velocity but the force is zero?

it is involved the concept of inertia ?? when a plane is flying on the sky , sometimes it will remain the constant velocity,right?and the force is balanced therefore , it does not have any force? why the plane can keep moving at the constant velocity ? due to inertia ? :confused::confused:
