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.
Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.For the special case of straight line motion in the x direction, the average velocity takes the form:he units for velocity can be implied from the definition to be meters/second or in general any distance unit over any time unit. You can approach an expression for the instantaneous velocity at any point on the path by taking the limit as the time interval gets smaller and smaller.
