👉 In physics, a flexion is defined as an extension of a body's length in response to a change in its shape or orientation. This can occur when a body is stretched or compressed in some way, such as under pressure or due to internal forces. For example, if a rubber band is stretched, it will become more flexible because the stretching causes it to extend and return to its original length after being compressed. Similarly, an elastic band that has been compressed can be flexed by applying force
