Elastic forces are the forces that allow materials to return to their original shape after being stretched or compressed. This property is commonly seen in objects like rubber bands and springs. When you pull on a rubber band, it stretches, but once you release it, the elastic force pulls it back to its original length. These forces are governed by Hooke's Law, which states that the force exerted by an elastic material is proportional to the amount it is deformed. Elastic forces play a crucial role in various applications, from engineering to everyday items like bouncy balls and mattresses.
