This read-only variable returns the x component of the
collision normal corresponding to the phy_collision_x array value.
For each contact point there is an associated contact normal (which
is usually the same normal for all points of contact in the
collision). This contact normal is a unit vector that points from
one instance in the collision to another, and can be used, for
example, to calculate the correct "push" direction to resolve
NOTE: This variable is only available in the collision event of a physics enabled instance.

with (instance_create(x, y, obj_Debris)
physics_apply_local_impulse(0, 0, other.phy_col_normal_x, other.phy_col_normal_y);
The above code uses the contact normal to set the direction of movement for an instance created in the collision event between two physics enabled instances.
