Experiment 2: Hooke's law - Modern Mechanics - phy100 / phy172

Hello everyone! In this post, I will explain everything that is related to Hooke's law experiment.

AUM - Modern Mechanics - phy100 / phy172 - Fall 2016 - Experiment 2 : Hooke's law

Group assessment questions:

# There are three tables that you will be asked to fill inside. For each table, we will find the graph as well. But for only one of these table, we will have to find the slope as well ( Finding the slope is so easy. Don't worry!)

Table 1 :

Table 2 :

Table 3 :

# Mention some errors that could happen during Hooke's law.

# Find the percentage error

Percentage error =  | ( theoretical - experimental ) / ( theoretical )  | * 100 

# Sometime you have a load on the spring, but there is no compression or stretch-ness. What is the reason for that?

# What is the relationship between the k and each spring?

Individual assessment questions : ( multiple choice questions )

# What is k? Stiffness

# What is the unit for k? N/m which means Newton per meter

# What is the Δk? Absolute error(?)

# How can we calculate the range for k?
Range = Kmax - Kmin (the unit is N/m which is Newton per meter)

# What is the name of the spring that stretch under the effect of a load?

# (For the tables you found at the group assessment) In which spring, the pre load will be equal to zero?

# What is Lo? the relaxed length

# At the long spring, is the L bigger than L node?

 Conversion:

You need to know some conversion to be able to do this experiment. How to covert between:

# millimeter (mm) to meter (m)

in every 1 meter (m) there is 1000 millimeter (mm) so to convert from mm to m, you simply need to divide by 1000.

My notes:

And that's it for this experiment. If I wrote something wrong, just correct me please. And if you know the answers for some of the questions that I did not solve (cuz' I am not sure of the answer), please tell me. Thank you all and wish you the best!
