In Godot is it possible to apply force or set the velocity of a rigidbody or a kinematicbody on local axis? If so, how can you do it? Thank you for your time.

You need to use the transform of the rigidbody to convert the local axis to a global axis:

var forcemult=20
var direction= Vector3(0,0,-1) #example: direction in -z
var global_direction = global_transform.basis.xform(relOffset)
apply_impulse(Vector3(0,0,0), global_direction * forcemult) #apply to bodies center

I used global_transform because this also directly transforms the axis when the body is child of another body.
If you want to transform a global value back to a local then use global_transform.basis.xform_inv(vector)

(Doesn't have to be a RigidBody, any Object derived from Spatial has a transform)
