That all depends on the strength and direction of the force.
If the object is already "falling", then there must already be the force of gravity
acting on it. The effect of any other force will depend on how the strength and
direction of the other force relates to the strength and direction of the gravitational
force.
-- If the new force is directed up, it will slow the falling object, and possibly even
make it stop falling and start rising.
-- If the new force is directed down, it will make the falling object fall faster.
-- If the new force is horizontal, it will make the object move horizontally as well as
continuing to fall.
-- If the new force is horizontal and strong enough, it will place the falling object into
Earth orbit.
When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.
Gravity is the force primarily involved with a falling object. It pulls the object downward towards the center of the Earth.
When an object is falling toward Earth, the force pushing up on the object is gravity, which is pulling the object downward towards the Earth's center. There is no active force pushing the object up as it falls.
Gravity is forcing an object to fall to the ground. Another force is friction from air pressure on the falling object.
Gravity
The force that opposes the downward motion of a falling object is air resistance, also known as drag force. This force acts in the opposite direction to the motion of the object and increases with the speed of the object.
You can calculate the force of a falling object using the formula: Force = mass x acceleration due to gravity. The acceleration due to gravity on Earth is approximately 9.81 m/s^2. Simply multiply the mass of the object by 9.81 to find the force of the object falling.
Nothing is opposing an object falling to earth. Gravity is causing an object to fall back to earth which is opposing the object from leaving earht. If anything the force that opposes gravity is the force at which an object is projected.
The shape of the object and the density of the gas that the object is falling through.
