Rubber Band Power [SLQ Wiki]

Not all rubber bands are the same, and those made from natural latex have the best properties for use as energy storage devices. Rubber bands also come in a wide range of sizes and thicknesses, and as a general rule the greater the volume of rubber in the band, the more energy it can store. Longer bands will store more energy than short ones

Elastic Energy

Elastic energy. Elastic energy is energy stored in an object when there is a temporary strain on it – like in a coiled spring or a stretched elastic band.. The energy is stored in the bonds between atoms.The bonds absorb energy as they are put under stress and release the energy as they relax (when the object returns to its original shape).

What are the forces acting on a catapult?

Stored Energy Methods (Other Than Rechargeable Batteries)

Humans have long searched for a way to store energy. One of the major things that''s been holding up electric cars is battery technology — when you compare batteries to gasoline, the differences are huge.. For example, an electric car might carry 1,000 pounds (454 kg) of lead-acid batteries that take several hours to recharge and might give the car a 100-mile

What is elastic potential energy?

Exercise 3: Figure 3 shows a stress vs strain plot for a rubber band. As it is stretched (loaded), the curve takes the upper path. Because the rubber band is not ideal, it delivers less force for a given extension when relaxing back (unloaded). The purple shaded area represents the elastic potential energy at maximum extension.
