Question

why is it easier to open a door by applying the force at the end of it?​

Answer 1

Explanation:

It is easier to open the door by applying force at its free end because the increased perpendicular distance decreases the amount of force required to open the door as the moment of force is the product of force and the perpendicular distance.

Answer 2

Answer:

Due to the application of torque.

Explanation:

Torque or couple forces are forces that act perpendicular to the surface of the object in opposite direction, it can also be defined as the product of force and perpendicular distance, is easier to open the door by applying force at its free end because the increased perpendicular distance decreases the amount of force required to open the door.
