Hooke's Law Flashcards
What is Hooke’s Law?
The extension of a spring is directly proportional to the force applied provided its limit of proportionality is not exceeded.
What is the Equation of Force applied?
F(N) = k(N/m) x Delta (change in) (m)
What does limit of proportionality mean?
It means that the material starts to behave in a non linear way and will no longer continue to deform and be able to regain shape.
What is a independent Variable?
The variable you CHANGE to see what happens.
Put it on your x-Axis
What is the dependant variable?
The variable you MEASURE
Put it on your Y-Axis
What is a control Variable ?
A variable that must be kept the SAME to prevent affecting your results.
What is the Independent Variable in Hooke’s Law experiment ?
The mass of weights
What is the Control Variable in Hooke’s Law experiment ?
The spring
What is the dependant Variable in Hooke’s Law experiment ?
The extension of the spring
What is the first instruction of making Hooke’s Law experiment?
Set up the equipment like shown in the diagram
What is the second instruction of making Hooke’s Law experiment?
Make sure the spring is high on the clamp stand so that it does not touch the table when weight is added.
What is the third instruction of making Hooke’s Law experiment?
Measure the length of spring with no,weights added.
What is the fourth instruction of making Hooke’s Law experiment?
Add 1.0N of weight to the spring and measure the new length
What is the fifth instruction of making Hooke’s Law experiment?
Repeat until a total of 6N is added.
What is the sixth instruction of making Hooke’s Law experiment?
Repeat the experiment 3 times and calculate an average for your results.
