So I did in an experiment and the results I got were the potential energy when the spring compresses is 0 and when it stretches is 1.42. This spring is vertical and has a 250 gram spring attached to it. I was very confused when i got these results because I thought the potential energy is higher when a spring compresses and when it stretches the potential energy turns into Kinetic energy.
Im sorry i meant it has a 250 g weight
Anyone!!
The PE is maximum when the spring is compressed or stretched. KE develops when the spring is moving.
KE+ PE= constant.
So, at the neutral point, where PE is zero, that is where KE is maximum, ie, it is moving fastest at that point.

To understand the potential energy of a spring and the confusion you encountered, let's break it down step by step.
First, let's clarify that the potential energy of a spring is given by the formula:
Potential Energy (PE) = (1/2) * k * x^2
Where:
- PE is the potential energy of the spring
- k is the spring constant (a measure of the stiffness of the spring)
- x is the displacement from the equilibrium position of the spring
In your experiment, you mentioned that when the spring compresses, the potential energy is 0, and when it stretches, the potential energy is 1.42. This information raises some questions, as it seems counterintuitive.
One possible explanation for this discrepancy could be an incorrect measurement or calculation. Make sure to double-check your data and calculations to ensure accuracy.
Alternatively, there may be external factors influencing the spring's behavior. For instance, if the spring is experiencing external forces (such as gravity or friction), they could affect the potential energy, causing unexpected results. Ensure your experiment is controlled, and there are no external forces impacting your setup.
Lastly, it's important to note that potential energy does indeed increase when a spring compresses, and it converts into kinetic energy as the spring stretches back to its equilibrium position. This is consistent with the concept of conservation of energy.
In conclusion, recheck your measurements and calculations to ensure accuracy. Additionally, consider any external factors that could influence the spring's behavior.
