1. Gravity: This is the force that pulls the object downwards towards the Earth. It's a constant force that depends on the object's mass.

2. Air Resistance (Drag): This is the force that opposes the object's motion through the air. It depends on factors like the object's shape, size, and speed.

While falling, the object experiences both forces simultaneously. Gravity pulls it down, while air resistance pushes against its movement. The balance between these two forces determines the object's acceleration and terminal velocity.
