1: Stretching a helical spring
What is the relationship between the force used
to stretch a spring and the subsequent extension?
Set the experiment up as shown in the next slide
- Note the position of the bottom of the coil spring.
- Put one, two, three weights on the spring and note down the number of weights, the force on the spring and the corresponding extension (table)
- Make a graph of your measurements
- Option: two identical springs connected serially (or parallel)
