Elastic Force- Elastic force is measured in newtons. It is used by a object with elasticity being stretched and measured by the amount of pressure that is being pulled by the object. The object always wants to go back to it's original shape, so it depends on how thick or thin the object is. (In other words the stretchiness). Our class measured the elastic force of a rubberband. Some of our rubberbands were thicker and harder to pull. Some were very stretchy. The more stretchy the rubberband the less elastic force. Before this, i would have wrote "I don't know" on a test, but now i would get full credit on the question. Thank You Mr.G!! :)
