A metaphor is a figurative language device that represents one thing as if it were another, or compares two things not normally viewed as similar, such as time is a thief. This comparison draws attention to the way time is quick and stealthy. Simile
Velocity is the rate of motion, speed or action. An example of velocity is a car driving at 75 miles per hour. velocity. pl. velocity. pl. Rapidity or speed of motion; swiftness. Physics A vector quantity whose magnitude is a body's speed and whose direction is the body's direction of motion.
By Andrew Zimmerman Jones. Definition: Velocity is a vector measurement of the rate and direction of motion or, in other terms, the rate and direction of the change in the position of an object.The scalar (absolute value) magnitude of the velocity vector is the speed of the motion.In calculus terms, velocity is the first derivative of position with respect to time. The most common way to calculate the constant velocity of an object moving in a straight line is with the formula:he scalar (absolute value) magnitude of the velocity vector is the speed of the motion. In calculus terms, velocity is the first derivative of position with respect to time. The most common way to calculate the constant velocity of an object moving in a straight line is with the formula:
