为什么反弹？

在很多领域，我们都会遇到“反弹”这个词。反弹可以是指某个物体从受力的方向相反的方向弹回，也可以指一种心理上的反抗或反应。那么，为什么会出现反弹呢？

首先，反弹是物体本身属性的体现。任何物体都会对作用力产生反应，这种反应通常会沿着作用力的相反方向发生。当一个物体受到外力作用而发生形变时，它会产生一个与外力方向相反的弹力，这个弹力会导致物体向原来的状态恢复，即反弹。英文翻译为：Why Rebound?

Rebound can refer to the physical phenomenon of an object bouncing back from the opposite direction of an applied force, as well as a psychological reaction or response. So, why does rebound occur?

Firstly, rebound is an embodiment of an object's inherent properties. Any object will react to external forces, and this reaction usually occurs in the opposite direction of the force. When an object undergoes deformation due to external forces, it will generate a rebound force that is opposite to the direction of the external force. This rebound force causes the object to recover its original state, known as rebound.
