Instantaneous Speed and Direction

Instantaneous velocity describes how fast an object is moving at a specific instant. It gives the motion of a particle at one point in time or at one point along its path. Average velocity over a time interval cannot show this level of detail.

Instantaneous velocity, often written as v x , is the...

The average velocity of an object cannot tell us how fast or in what direction the object was moving at any given time. To identify this, we need the velocity at a specific instant of time or the instantaneous velocity.

The instantaneous velocity is the limit of the average velocity as the time interval approaches zero, or the derivative ...
