    Energy Friction Loss
Click For Summary
SUMMARY

The discussion centers on the concept of energy and its relationship with friction losses in motion. Participants clarify that energy is a property of physical objects, not a standalone entity. They conclude that if a mass moves without any friction or resistance, it will maintain its speed indefinitely. The principle of inertia is highlighted, stating that a body in motion will remain in motion unless acted upon by an external force.

PREREQUISITES
  • Understanding of kinetic energy and its properties
  • Familiarity with Newton's First Law of Motion
  • Basic knowledge of friction and resistance in physics
  • Concept of inertia in classical mechanics
NEXT STEPS
  • Study the implications of Newton's First Law of Motion in various contexts
  • Explore the concept of energy conservation in closed systems
  • Investigate real-world applications of frictionless motion
  • Learn about the mathematical modeling of motion in physics
USEFUL FOR

Students of physics, educators explaining classical mechanics, and anyone interested in the principles of motion and energy conservation.

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.

If the energy itself
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.
