Besides the elongation, what other factors may affect the spring force when the spring is stretched?

After learning the knowledge of elasticity, Xiao Xuan found that when the spring is pulled, the greater the pulling force, the greater the elongation of the spring. So Xiao Xuan put forward a conjecture: the elongation of the spring is directly proportional to the tension. The experimental platform has been equipped with the following equipment: a spring that meets the experimental requirements, an iron frame, a scale and six hook codes with a mass of 50g. Please design an experiment with the above experimental equipment to explore: "Is the elongation (δ L) of the spring proportional to the pulling force (F)?" Requirements: (1) Please write down the experimental steps (you can draw a schematic diagram to help explain); (2) Draw the experimental data record table.

Answer (find the homework answer -->>；; On the Rubik's Cube)

(1) experimental steps:

① Hang the spring on the bracket of the iron frame, measure the length L0 of the spring with a scale, and record the data in the table.

② Hang a hook code on the hook below the spring, measure the length l of the spring with a scale, and record the mass m of the hook code and the length l of the spring in the table.

(3) Take step (2) as an example, hang 2, 3, 4, 5 and 6 hook codes under the spring in turn, measure the length l of the spring with a scale every time, and record the total mass m of each hook code and the corresponding spring length l in the table.

(4) Using the formula f = g = mg, calculate the tensile forces f of the six springs respectively and record them in the table.

Using the formula Δ δL = L-l0, the elongation Δ l of the sixth spring is calculated and recorded in the table respectively.

(2) experimental data record form:

Test analysis: When designing an experiment, you need to know which physical quantities to measure and which instruments to use, and arrange them in the order of measurement, so as to get the general experimental steps. In the process, we should pay attention to the standardization of operation and the accuracy of language, and the measured physical quantities should be represented by symbols.
