Question

What are the oscillations? Pre-Laboratory Work: Part P-l: Using a spring attached to a vertical support, develop an experimental procedure to determine the spring constant for the spring hanging from the vertical support using a spring, a set of weights with hangers, and a motion sensor. Your method should stretch the spring by no more than 5 centimeters. Describe this method in detail. Because this is being determined from experimental data, which strategies or approaches will you use to get the most accurate value possible for this particular spring's spring constant? Explain your reasoning explicitly. Do not assume your instructor knows anything. Every spring has a spring constant (k). The spring constant is determined by dividing the magnitude of the force that causes an expansion of the spring by the amount that the spring expands. k = Delta F/d.

Explanation / Answer

It is an experimental study , so you have to perform experiment to get data:

Here I will provide you the procedure :

We know that spring constant can be determined as K = F/d

F is the force that us causing the spring to expand and d is the amount by which spring expands.

We will increase the load ( hanging mass) slightly and record the expansion by scale

You should generate such table to observe your data

For example:

1. Load = 2 kg ,

Then force = 2×9.81 = 19.62 N

Let expansion = 2 cm

Then spring constant = F/d = 19.62/(2×10-2) = 981 N/m

2. Now we increase the load , new load is 4 kg

And resulting force = 4× 9.81 = 39.24 N

Let expansion = 4 cm

Then k = F/d = (39.24-19.62)/2

By this way .. You perform upto 5 times and then record the results .

Hope it will help you to perform task

Load Force(N) Expand(cm) K
