The potential difference between two points in an electric circuit is the work done when a coulomb of charge passes between the points. You can calculate the size of a potential difference using this equation: V = W ÷ Q. V is the potential difference in volts, V. W is the work done (energy transferred) in joules, J.Voltage, electric potential difference, electric pressure or electric tension is the difference in electric potential between two points. The voltage between two points is equal to the work done per unit of charge against a static electric field to move a test charge between two points. This is measured in units of volts read less

Is it possible, the displacement can be greater than the distance travelled by an object?
No, aa for euclidean space, the displacement is always greater than or equal to the distance travelled as goes by it's definition that it is the shortes way possible to reach from point A to point B. And...

Why does a swimmer push the water backwards?
According to newton's 3rd law of motion in each and every action there is an equal and opposite force. So if he push the water backwards then according to the above principle or law he will be able to move forward.

If force is acting on a moving body perpendicular to the direction of motion, then what will be its effect on the speed and direction of the body?
The magnitude of velocity shall decrease and direction shall be same till it comes to rest, afterwards it shall move in direction of force with acceleration due to the applied force.
