GENERAL KNOWLEDGE

Detailed explanation-1: -Velocity is the rate at which the position changes. The average velocity is the displacement or position change (a vector quantity) per time ratio.

Detailed explanation-2: -acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down.

Detailed explanation-3: -Motion is a change in position measured by distance and time. Speed tells us the rate at which an object moves. Velocity tells us the speed and direction of a moving object.

Detailed explanation-4: -The rate of change of displacement is known as velocity. It is a vector quantity as it has magnitude as well as direction.
