I have a question about energy & ignoring friction losses

If the energy itself ignores loss resistance friction and the energy moves forward, can infinity go far at a constant speed?

If a mass is moving forwards with kinetic energy, and assuming there is no loss of energy to friction, then it will go on until the end of time, or until it hits something.

Try putting your question in another way. You have managed to confused us totally so far about what you actually want to know.

Energy is not a physical thing. It's a property of other things. A block or a particle can move forward, and it can have energy, but not 'the energy itself'.

If we assume a block of some sort is sliding across an infinite plane with zero resistance of any type and without any other force applied, then yes, it will continue to slide forever at a constant speed. Does that answer your question?

Is this what you're after?
Newton's First Law of Motion said:
A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by a force.
