Actually, I really knew about this but, I would like to tell all people that do not do a crime...! so that we will be in ONE peace! Please spread this to your friends..! or post this on twitter..! I really appreciate that! Well, here are the examples: a motorcycle is doing an action when the driver is going on an unidentified distance. So, the driver is doing an action while he is on a distance force!!! Did I answer your question? (from Rhiyan Mae)
One example of an action-at-a-distance force is gravity. Gravity is a force that acts between two objects without physical contact, pulling them towards each other based on their masses and distance.
The magnetic force is considered an action-at-a-distance force because it can act on objects without physical contact between them. It can attract or repel objects at a distance through magnetic fields, similar to how gravitational forces act between objects without the need for direct contact.
No, that situation would not be considered an action-at-a-distance force. An action-at-a-distance force is a force that can affect an object without coming into direct contact with it, like gravity. In the case of the birds pulling on a worm, the force is being applied through direct contact with the worm.
The formula for moment arm is distance between the point of rotation and the line of action of the force. Mathematically, it can be represented as the cross product of the position vector and the force vector.
Gravitational force Magnetic force Electric force Nuclear force Electrostatic force Tension force in a rope Friction force Spring force Drag force Buoyant force
Without going into advanced physics, just consider it an action at a distance. The objects don't need to be touching directly for the force to be transmitted.

That's the torque due to the force.

Gravity is action at a distance, a non contact force
Contact force means that objects need to be in contact for there to be a force. "Action at a distance" means the objects do NOT need to touch one another directly.
It's not. For there to be friction, there must be nodistance between the objects (surfaces) in question. Action at a distance forces are forces like gravity and electromagnetism. These forces can affect the state of an object with no media attached to the object.

To calculate the moment of a force, you multiply the magnitude of the force by the perpendicular distance from the point of rotation (or pivot) to the line of action of the force. The formula is moment = force x distance. Moments are measured in units of force multiplied by distance (Newton-meters or foot-pounds).
The distance from the applied force to the fulcrum is called the effort arm or lever arm. It is the perpendicular distance between the line of action of the force and the fulcrum in a lever system. The length of the effort arm affects the mechanical advantage of the lever.
