an object being pulled to earth by gravity will have the force of air pushing back opposite directions
No, a object being pulled to Earth by gravity will not have the force of air pushing back in opposite directions. The force of air pushing against an object is called air resistance or drag, and it only becomes significant when the object is moving through the air at a high speed.
When an object is falling towards the Earth, the main force acting on it is gravity, which pulls the object downwards. This force is always directed towards the center of the Earth. Gravity does not depend on the presence or absence of air; it affects all objects in the same way.
Air resistance, on the other hand, only comes into play when an object is moving through the air. As the object moves, it encounters air molecules which exert a resistance force that opposes the motion. However, this force is not the result of air "pushing back" in opposite directions. Instead, it is a result of the interaction between the object and the air molecules.
To determine the forces acting on an object being pulled to Earth by gravity, you would need to consider the gravitational force pulling it downwards and any other forces that may be present, such as air resistance if the object is moving through the air. The net force acting on the object will determine its acceleration or deceleration.
