Question

What is the difference between rate of change of position over time and rate of change of displacement over time??

Are they the same thing called velocity?

Answer 1

The rate of change in position of an object is just how fast its position is changing, or the velocity of said object. There are two types of rates of change that are commonly discussed: Average rate of change, and Instantaneous rate of change.


The rate of change of displacement with time is called velocity (not speed) since the displacement is a vector quantity therefore it is velocity which is also vector. Or you can also understand it in instantaneous form which is dv/dx.

Yes , both are velocity.
