Elastic force is when the force of a rubber band and other stretchy object stretches or expands at short or long distance. You can very the amount of force by the amount you expand the object. An example of elastic force is a sling shot. When you load it with a rock you would have to pull the rubberband lines back long enough so it will go a great distance. Then the force of the lines would sling it a certain direction. I learned that rubber bands are very stretchy and have a lot of force.
