An example of an influence or power that can cause a change in an object or system is gravity.
In a practical scenario, consider a fruit hanging from a tree. The force of gravity acts on the fruit, pulling it downward. If the fruit becomes overripe and loses its structural integrity, gravity will cause it to fall to the ground, changing its state from being attached to the tree to lying on the ground. This illustrates how the gravitational force can influence the position and state of an object in a system.
