B I have a question about energy & ignoring friction losses

Click For Summary
The discussion centers on the concept of energy in relation to motion and friction. It asserts that if a mass moves forward without any energy loss due to friction, it could theoretically continue indefinitely at a constant speed. Participants clarify that energy is not a physical entity but a property of objects in motion. The conversation emphasizes that a body will maintain its state of motion unless acted upon by an external force. Ultimately, the idea of infinite motion without resistance is explored, affirming that it is possible under ideal conditions.

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?

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.
 
I'm setting up an analog power supply. I have the transformer bridge and filter capacitors so far. The transformer puts out 30 volts. I am currently using two parallel power transistors and a variable resistor to set the output. It also has a meter to monitor voltage. The question is this. How do I set up a single transistor to remove whats left of the ripple after the filter capacitors. It has to vary along with the control transistors to be constant in its ripple removing. The bases of the...
