What is OPFOR forces analysis?
An opposing force (alternatively enemy force, abbreviated OPFOR or OpFor) is a military unit tasked with representing an enemy, usually for training purposes in war game scenarios. The related concept of aggressor squadron is used by some air forces. At a basic level, a unit might serve as an opposing force for a single scenario, differing from ...
The friction force is the force exerted by a surface as an object moves across it or makes an effort to move across it. There are at least two types of friction force - sliding and static friction. Though it is not always the case, the friction force often opposes the motion of an object.

- There are two kinds of friction which are kinetic friction and static friction. Kinetic friction exists when there is relative motion between two s...
- as long as it is the same, it will act on the rock with the same net force
- Since the surfaces in contact are the same, the *coefficients of static and kinetic friction* are the same in all cases. This can probably be given...
- If they have a non-zero net force then the are unbalanced.
- Force is the acceleration of the mass, 1 Newton is the necessary force that's used to move an object with 1kg of mass at a 1m/s²: m(kg) a(m/s²) F=m...
- Terminal velocity is the velocity at which the resistance and or drag force on an object from a fluis that it is moving through is equal and opposi...
- You are absolutely right. If this were in the real world, both characters would have to fight friction in order to push the rock. However, this is...
- This is an interesting problem, never seen one like it. I know the answer but won't give it to you, but here is a hint. Find the combination of thr...
- Let's say there is a tiny rock, small enough to be carried in a person's hand. Then, they find some soft soil, the person pushes with a force of 10...

Opposing Force (OPFOR) that exists for the purpose of training U.S. forces for potential combat operations. This OPFOR reflects the characteristics of military and paramilitary forces that may be present in the contemporary operational environment (COE). Like those real-world threats, the OPFOR
There are two forces resulting from this interaction - a force on the chair and a force on your body. These two forces are called action and reaction forces and are the subject of Newton's third law of motion. Formally stated, Newton's third law is: For every action, there is an equal and opposite reaction.
