River Boat Vectors and Projectiles
Suppose the motion of the river boats below. Within that case, the boat is heading across the river. Inside the top case, the presence of a current causes the boat to travel downstream as it at the same time moves across the river; the result is in which it reaches the opposite shore at a point downstream from whereas it begins. In the bottom case, the absence of a current means in which the boat moves straight across the river; it ultimately reaches a point on the opposite shore directly across from whereas it begins. It is significant to note that the current is what carries the boat down the stream; it is not the motor of the boat in which gives its downstream motion.
It is the difference among potential at two points of a conductor. Please note that by potential(at a point A) ,we actually mean potential difference among point A and another
