You Can Investigate Hooke’s Law with a Spring Flashcards
What do you do first?
Measure the length of the spring when no load is applied
What do you need to ensure for the first step?
That the ruler is vertical and you measure the spring at eye level
What do you do second?
Add one mass as a time and allow the spring to come to rest, then measure the new length
What is the extension?
The change in length from the original length
How long do you repeat this process for?
Until you have enough measurements (no fewer than 6)
What do you do once you’re done?
Repeat the experiment and calculate an average value for the length of the spring for each applied weight
What do you plot on the vertical axis of your graph, and what do you plot on the horizontal?
Vertical - show force
Horizontal - total extension
What should you find?
That the same increase In the weight on the end of the spring always leads to the same increase in extension - Hooke’s las in action
What do you repeat the experiment using?
A metal wire or a rubber band instead of the spring
