Velocity

Velocity is a measurement of speed in a certain direction of motion. It is a fundamental concept in kinematics, the branch of classical mechanics that describes the motion of physical objects. Velocit
As a change of direction occurs while the racing cars turn on the curved track, their velocity is not constant even if their speed is.
Acceleration

In physics, acceleration is a measure of how fast and in what direction an object's speed and direction of motion are changing. It is defined as the rate of change of the velocity. Like velocity, acce

…scalar, whereas "5 metres per second east" is a vector. If there is a change in speed, direction or both, then the object is said to be undergoing an acceleration. The average velocity of an object over a period of time is its change in position, Δ s , divided by the duration of the period, Δ t , given mathematically…
Drag racing is a sport in which specially-built vehicles compete to be the fastest to accelerate from a standing start.
