Simple Harmonic Motion Equilibrium

AI Thread Summary
In simple harmonic motion, applying a continuous downward force on a mass hanging from a spring alters the system's equilibrium position, establishing a new point. If the force is not continuous and merely adds energy, such as a brief push, the original equilibrium remains unchanged. The discussion clarifies the distinction between continuous force application and transient energy addition. Participants acknowledge the confusion and refine their understanding of equilibrium in relation to external forces. The conversation emphasizes the importance of accurately defining forces in the context of harmonic motion.

I am a little confused with this subject. If you have a mass hanging from a spring, there is a specific equilibrium point, but what if you apply a force downwards on the mass, will this have an effect on the equilibrium position or will it remain the same?

thanks!

If the force is applied continuously, it would be added to the current downward force of the mass, and (Edit) the system would establish a new equilibrium point. Is that what you meant?

My first reply was poor to incorrect. I think when you said apply a force, you meant adding energy to the system, like pushing down on the mass. That would not change the equilibrium point. Sorry for being too hasty.:blushing:
 
yes that is what I meant, thanks!

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
