The student most likely studying transformation between potential and kinetic energy.
Potential energy is the stored energy in any object or system by virtue of its position or arrangement of parts.
Kinetic energy is a form of energy that an object or a particle has by reason of its motion.
When the rubber band is stretched between her fingers it is in the potential energy state. Ans she releases the rubber band, that time her hand is fighting against the rubber and potential energy is changing from potential energy to kinetic energy.
Hence, the student most likely studying the transformation between potential and kinetic energy.
