2 horses pull against a rope in the opposite direction with forces of 100 newtons is an example what?

This is an example of balanced forces.

Here's why:

* Equal and Opposite: The horses are pulling with the same force (100 Newtons) but in opposite directions. This means the forces are equal in magnitude and opposite in direction.

* Net Force: Because the forces are balanced, the net force on the rope is zero. This means the rope will not move.

Let me know if you'd like more examples of balanced or unbalanced forces!
