speed, change in distance with respect to time. Speed is a scalar rather than a vector U [−3,1] and V [5,2], one can add their corresponding components to find the resultant vector R [2,3], or one can graph U and V on a set of coordinate axes and complete the parallelogram formed with U and V .....

If during time t a body travels over a distance s, then the average speed of that body is equal to s/t. The speed and direction of a body's motion together determine the body's velocity velocity, change in displacement with respect to time. Displacement is the vector counterpart of distance, having both magnitude and direction. Velocity is therefore also a vector quantity. The magnitude of velocity is known as the speed of a body. .....

| Had they been able to subdue the frightful pressure of the initiatory speed of more than 11,000 yards, which was enough to traverse Paris or New York in a second? Under this the Abraham Lincoln attained the mean speed of nearly eighteen knots and a third an hour-- a considerable speed, but, nevertheless, insufficient to grapple with this gigantic cetacean. I know that this would sometimes involve a slight loss of speed in the chase; but long experience in various whalemen of more than one nation has convinced me that in the vast majority of failures in the fishery, it has not by any means been so much the speed of the whale as the before described exhaustion of the harpooneer that has caused them. |
