gravity
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.
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.
It's terminal velocity. This depends primarily on the object's cross section, its aerodynamic coefficient, and the density of the air it's falling through.
When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.
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.
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.
