      I’m not sure what you mean here. A force is a thing which is applied to an object and when you do so the object will move in the direction of a force. In a car the engine applies a force to the wheels and drives it forwards so if you have two cars with the forces applied in opposite directions… well you know what happens when they crash!

      Like Andrew says, a force is an influence on a mass to undergo a certain change. Two forces wouldn’t so much collide as they would both be exerting a force on the same mass, and it is that mass which would be affected.

      That would depend on the masses and the momentum of the two objects!!!!!

      More interestingly, what happens when an unstoppable force acts uppon an immovable object?

      Black holes?

      Forces can only interact with objects, two forces even if they are they same type of force don’t interact. I.e. gravity of the sun and the gravity of the earth just add up at some point. The force carriers are called bosons and they can quite happily live in the same space with out interacting ( I think)
