Average Speed and Average Velocity

The average speed in a time interval is defined as the total distance travelled by the particle divided by the time interval

INSTANTANEOUS SPEED AND INSTANTANEOUS VELOCITY

Suppose a particle moves in such a way that it covers different distances in equal time intervals. Its speed is then said to be variable and its speed at a particular instant is called the instantaneous speed.

AVERAGE ACCELERATION AND INSTANTANEOUS ACCELERATION

Very often, the velocity of a particle changes either in magnitude, in direction, or both as the motion proceeds. The body is then said to have an acceleration. The acceleration is defined as the time rate of change of velocity.
