The movement of door is a type of rotational movement due to the hinge connected to it.
And according to the torque theory related with the rotational force,we came to know that more amount of force is necessary when we are applying the force near the central portion of the rotation.
Same happens for the movement of the door also.
That's why less amount of force is necessary to open a door when the force is applied on the free side of the door.

It is easier to open a door by applying the force at the free end of it because of the larger the perpendicular distance, less is the force needed to turn the body.
