Hooke's Law : Extension of a spring
Investigate Hooke's law in doing an experiment on springs.
Assessment on Criterion C : Spring Constant
When: Joy 17/3
Trust 18/3
Practice and Rubric
- Your practice experiment should be recorded in your notebook the same as is written on "practice and rubric" document above.
Independent variables: The load or weight on each spring.
Dependent variable: The extension of the spring.
Be careful to not over extend the spring otherwise you break it's elastic limit.
Use graph paper to graph the Force versus extension graphs. Notice that the Independent variable is on the y-axis. Why is that?
Calculate the spring constant for the spring.
Write down Hooke's law for your spring.
Experiment 2: Use 2 springs side by side (parallel) and see if it follows Hooke's law.
Experiment 3: Use 2 springs attached to each other in series. eg. One spring attached to another spring then attached to a load.
