Why's Applied Force Plotted On Vertical Axis?

AI Thread Summary
In a Hooke's Law experiment, applied force is plotted on the vertical axis despite being the independent variable because it aligns with the linear equation format of Fx = kx, where Fx represents the dependent variable. This setup allows for clear visualization of the relationship between force and displacement. The negative sign in the equation indicates that as displacement increases, the spring exerts an opposing force. Additionally, this graphing method facilitates calculations of the spring constant and work done by dividing force by displacement. Overall, the vertical axis representation effectively illustrates the dynamics of spring behavior under applied forces.

Homework Statement



Explain why applied force is plotted on the vertical axis of the graph even though it is the independent variable in a Hooke's Law experiment (involving a mass being attached to the spring)

Homework Equations



Fx = kx

The Attempt at a Solution



Maybe it's because the equation Fx = kx is in the form of y=x where Fx is the y and the k value is the slope.

You'd have to give more background or information. I am not even used to force being graphed, except for an impulse.
 
Force is the dependent variable. Hookes law is for the spring. Sure if you change the amount of force you apply the displacement changes, but that's not the point. The further the displacement, the more the spring pulls back. This is the reason for the negative sign. With this graph setup, you can divide F/x to find the spring constant and multiply F*x to find the work done
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
