1.What are the spring constant (k) is for spring 1 and spring 2? What are the units of k? Which spring is stiffer? Fs= kx
k is the spring constant and it is measured in N/m or in kg•m/s2 Spring constant for Spring 1= .49=k(.01)= 49 k=49 N/m
Spring constant for spring 2= .49=k(.02)= 24.5 k=24.5 N/m Spring 1 is stiffer; you can see that by the smaller change in spring length, and the higher spring constant.

2.Does your data fall neatly on your best-fit line? What are the possible sources of error in your measurements? Our data falls fairly neatly on our best-fit line. The possible sources of error are incorrect positioning of the ruler, and possible incorrect reading of the measurements.

3.When we draw a line past the data points measured, we call that extrapolation. Why is this not advised in this case? Extrapolation is not advised in this case because extrapolating gets less precise measurements. Since the measurements here might not be 100% accurate in the first place, assumed measurements would not add to the data. There will be more uncertainty between the extrapolated points.

4.Why are the cables of a suspension bridge elastic? The cables are elastic so they act like springs and “bounce” back. This way there isn’t too much strain on the cables as heavy vehicles pass over it. If the cables are too stiff, then the brittleness will cause it to snap. The elastic allows for proper function.

5.Hooke’s Law is a direct relationship. What does this mean? This means that Hooke’s law is a direct relationship between an applied force and the change in the spring’s length due to that applied force. The more weight is placed on the spring, the greater the spring will stretch.

...Aim: To determine a value for the spring’s force constant, k.
Introduction:
Hooke’sLaw indicates the relationship between the amount of extension, e, of a spring to the size of the force, F, acing on it.
This relationship may be written as :-
F = ke
F = ke
where k is a constant for which particular spring you are using. It is the force constant of the spring.
* The force applying on the spring, F, is denoted by Newton in SI Units. (N)
* The...

...HOOKE’SLAW EXPERIMENT
Aim: The aim of this experiment is to determine the force constant (k) of the particular spring used.
Introduction
Hooke’sLaw: Hooke’sLaw is a law that shows the relationship between the forces applied to a spring and change in its length (extension). The relation is best explained by the equation:
F= -k Δx
F: Is force applied to the spring this can be...

Theory
For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k.
Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to...
