Velocity is the _______________ that occurs in
Answers
Answer :
The velocity of an object is the rate of change of its position with respect to a frame of reference, and is a function of time. Velocity is equivalent to a specification of an object's speed and direction of motion (e.g. 60 km/h to the north).
Average velocity is defined to be the change in position divided by the time of travel.
\Large v_{avg}=\dfrac{\Delta x}{\Delta t}=\dfrac{x_f-x_0}{t_f-t_0}v
