Definitions:

Pushing Effort

The force applied to an object in order to move it in a specific direction, often measured to assess efficiency in mechanical systems.

Pulling Effort

The force required to move or tow something, often measured to ensure the adequacy of a vehicle's towing capacity.

Force

Push or pull effort measured in units of weight. Force represents the ability to do work but this ability does not necessarily result in any work done; for instance, you can push all you like on a tractor/trailer combination but it is unlikely to move the vehicle. The formula for force (F) is calculated by multiplying pressure (P) by the area (A) it acts on. F=P*A.

Perfect Vacuum

A theoretical state where a space is completely devoid of matter, including air or any other gases, achieving a total absence of pressure.
