When pulled, stretchy objects such as rubber bands exert elastic force. The person in the picture is gently holding one end of the rubber band and pulling on the other end.
The person can feel the rubber band pulling back. The more the rubber band stretches, the harder it is to pull. How does the force exerted by the rubber band change as its length increases?
