The efficiency of a rubber band slingshot remains constant across different stretch lengths due to the relationship between kinetic energy and elastic potential energy. When the rubber band is stretched, it stores elastic potential energy, which is converted to kinetic energy upon release. The efficiency is close to 100% in ideal conditions, as the energy lost due to hysteresis—where some energy is converted into heat—is minimal. This phenomenon can be analyzed through the phases of stretching and releasing, confirming the consistent efficiency of the slingshot.
PREREQUISITESStudents in physics or engineering, educators explaining energy concepts, and hobbyists interested in the mechanics of slingshots and elastic materials.
Not sure I can answer it either, in the sense of a reasonable basis for predicting that result.CTHAEH said:Homework Statement
I need to explain for a lab, why the efficiency of a rubber band slingshot constant for different stretch lengths. I don't need math, just a general explanation of why kinetic energy of projectile/elastic potential energy in rubber band is constant.
Homework Equations
The Attempt at a Solution
I really couldn't think of anything. Please help
Possibly, but in that case one could look at loss, i.e. 1-efficiency, thereby exposing variation better.CWatters said:Perhaps a slingshot is close to ideal? In which case the efficiency is always close to 100%?
