Air resistance.
1. when you drop a feather and a hammer the feather falls slower than the hammer
Because the moon has essentially no atmosphere, there would be no drag on the feather when it falls. On earth, it would be quite a different matter. The significant surface area of the feather means that as it falls, the friction of the air on it provides significant opposing force to it as it falls. In the case of a falling hammer, the opposing force of air friction on the hammer is negligible compared to the force of gravity on it since the hammer is much heavier than the feather. Since there would be no drag on either item when dropped on the moon, the only force acting on either would be gravity and their acceleration would be only that of gravity with no opposing force to slow them down as they fell.
The feather falls slower because it has air restistance. The air pushes up on it. The rock falls faster because it's mass and how it doesn't have air resistance. Also, because toilet seats produce a gas, reacting with the feathers on a feather, making the feather rise.
Shining Force Feather happened in 2009.

The force of the hammer is much greater than the force of the nail. Gravity pulls down the hammer, hits the nail, and the nail forces up, but the force of gravity wins over the force pulling on the nail.
In physics, net force refers to the overall force acting on an object. A feather with no net force on it maintains constant velocity.
A hammer is used to apply force
The hammer exerts a force on the nail; the nail exerts a force on the hammer.
a feather with no net foce maintians constant what?
The greatest velocity any object can have on earth is it's terminal velocity. That means when the force of gravity is eventually overcome by the force of air resistance of the falling object. An example of this would be that a falling feather reaches its terminal velocity much quicker (and therefore falls much slower) than something that is more dense and aerodynamic, such as a bowling ball or a baby.
The effort force is where you are holding the hammer to pull the nail.
