Reasons for miscalculation of spring work and change in ke

[uknew]

can anyone help me in figuring out why i got different answers in my calculated value to my experiment value (or maybe its normal) when i calculated the aproximate distance a projectile would shoot up when i compressed a spring thru a distance. i calculated the spring constant and found the final velocity of the projectile once in projectile motion(which would make it its initial as a projectile).i checked the distance it traveled vertcally.compred it to my calculated one and they were very different. can anyone help explain why?friction, weight of the spring were not considered.thank

also how does cutting the spring change the stiffness or av. forfce exerted. ?will it go higher or the same?any help is good

Hooke's law is under idealized conditions that you probably broke by compressing the spring as far as possible - at least this is a typical thing to do when shooting things up with springs. A full description of the setup and how you extracted the spring constant would allow us to better spot the problem

There could be several reasons for the miscalculation of spring work and change in kinetic energy in your experiment. One possible reason could be errors in measurement or data entry. It is important to ensure that all measurements are accurate and correctly recorded to avoid any discrepancies in the results.

Another reason could be the presence of external factors that were not accounted for in the calculations. For example, air resistance or friction could have affected the motion of the projectile, causing it to travel a shorter distance than expected. The weight of the spring could also play a role in the accuracy of the calculations, as it could affect the amount of force applied to the projectile.

Additionally, it is important to consider the limitations of the equipment used in the experiment. If the spring is not perfectly linear or there are other factors that could affect its elasticity, it could lead to variations in the results.

To improve the accuracy of your calculations, it is important to carefully consider all possible factors and sources of error and take steps to minimize their impact on the results. This could include using more precise measuring tools, accounting for external factors, and ensuring the equipment is in optimal condition. It is also helpful to repeat the experiment multiple times to gather more data and reduce the influence of random errors.
