Air resistance and gravity are the main components.
-- gravity -- air resistance
It reduces the acceleration of the falling object due to friction.
When the upward and downward forces on a falling object are equal, the object reaches terminal velocity. At terminal velocity, the object stops accelerating and falls at a constant speed.
No, we cannot see all of the forces that affect an object because some forces, like gravity or magnetic forces, are invisible to the naked eye. However, we can observe the effects of these forces on the object's motion or behavior.
Gravity is one, and I believe that friction is the other. Friction here being caused by the resistance to motion of the fluid the object is falling in. Generally this is termed air resistance or drag and it is related to the object's velocity and cross section as well as the fluid's viscosity.
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
When an object is falling at terminal velocity, the forces of gravity pulling it downward and air resistance pushing upward are balanced. This results in a constant velocity for the object as it falls.
Gravitation and air resistance. There could be some electrostatic or magnetic forces there too, but those would depend on the composition of the object and the nature of what's floating around in the environment, so they're not always there. Gravitation and air resistance are always there.
The shape of the object and the density of the gas that the object is falling through.
The two forces acting on an object that is falling are gravity, which pulls the object downward towards the center of the Earth, and air resistance, which opposes the object's downward motion and slows its fall.
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.
