2 is the answer
2, Gravity and Friction (aka wind resistance). The body will reach terminal velocity when the air it is passing through creates enough friction so that it equals the force of gravity therefore stopping any further acceleration.
The two main forces acting on a falling object in Earth's atmosphere are gravity, which pulls the object downward, and air resistance (also known as drag), which opposes the object's motion and slows it down as it falls.
Air resistance and gravity.
The forces that affect the rate of a falling object are Gravity and Air Resistance. Gravity affects the speed and the velocity of the object by speeding it up as it falls closer to the earth, and Air resistance works against the object pushing against it.
On any planet with an atmosphere, gravity is counteracted by the force of air friction with the object that is falling. This is known as terminal velocity - the point at which the forces of air resistance and gravity balance.
The main forces acting on a falling object are gravity, which pulls the object downwards towards the center of the Earth, and air resistance, which opposes the motion of the object as it falls through the air.
The forces acting on the egg are gravity pulling it downwards and the normal force pushing it upwards. The normal force is exerted by the branch of the tree the egg is falling from, preventing it from falling through the branch.
The two forces acting on falling objects in Earth's atmosphere are gravity, which pulls objects downward towards the center of the Earth, and air resistance, which slows down the object's fall as it moves through the air.

The two main forces acting on a marble falling through oil are gravity, which pulls the marble downward towards the center of the Earth, and drag force, which acts in the opposite direction to slow down the marble's motion as it moves through the viscous fluid of the oil.
Gravity and air resistance.
The two forces acting on a falling object are gravity and air resistance. Gravity pulls the object downward, while air resistance acts in the opposite direction to slow down the object as it falls through the air.
