Is My Thinking Reasonable: A's Impact on Oscillator Motion

AI Thread Summary
A is identified as the primary factor influencing the amplitude of motion in an oscillator at resonance, while B, C, and D are fixed or dependent variables. Understanding the physics behind oscillators is crucial to grasp why A is the correct answer. The damping force, which is a characteristic of the oscillator, also plays a role in the overall motion. The discussion emphasizes the importance of analyzing these relationships to clarify the impact of A. Ultimately, the reasoning aligns with fundamental principles of oscillatory motion.

Homework Statement
A sinusoidal force with a given amplitude is applied to an oscillator. At resonance the amplitude of the oscillation is limited by:
A. the damping force
B. the initial amplitude
C. the initial velocity
D. the force of gravity
E. none of the above

The answer is A
Relevant Equations
F = -kx
I just want to check if my thinking is reasonable. Since B,C and D are all dependent or fixed by the oscillator, A is the only factor to affect the amplitude of the motion at resonance or even throughout the entire process?
 
Physics news on Phys.org
I think it would be better to know why the answer is A.
 
The damping force is also generally a property of the oscillator.

In order to deduce why A is the correct answer, you need to consider the actual physics of the oscillator.
 
Thank you all. I got it.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Correct statement about a reservoir with an outlet pipe'

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...

Thread 'A bead-mass oscillatory system problem'

I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
