Direction


Speed


Acceleration


Time

Detailed explanation1: Velocity: The rate of change of displacement of an object (displacement over elapsed time) is velocity. Velocity is a vector since it has both magnitude (called speed) and direction.
Detailed explanation2: The rate of change in displacement is referred to as velocity. In general, the velocity of an object changes during its motion. It is also called the firstorder derivative of displacement with respect to time. It can be expressed as v = d x d t .
Detailed explanation3: Rate of change of displacement with time is called Velocity.
Detailed explanation4: The rate of change of velocity is called acceleration. Acceleration is the ratio of change in velocity with time. The SI unit of acceleration is m/s2.
