Dynamics of rubber band stretch ejection
WebDec 17, 2024 · Why are hot rubber bands able to be stretched longer than cold rubber bands when acted upon by the same force? For example, a hot rubber band will stretch 10 cm when a weight it pulling it down, but a cold rubber band will stretch 5 cm when the same weight is pulling it down. Is it because of entropy? Or potential energy?

WebOct 4, 2024 · There are two ways that temperature affects the length of a stretched rubber band. The first is thermal expansion - an unstretched rubber band will, like most materials, tend to expand when heated. The second is a change to the Young's modulus - the proportion by which the rubber band will stretch when subject to a given stress or load. WebStretch the rubber band taut and start twisting (roll the rubber band between thumb and forefinger). The band becomes tight and knotted and filled with latent energy. Keep twisting, if you dare, until—crack!—the …
