Relative Motion

Important things: 

aAB=aA-aB                    “acceleration of  A with respect to B”

VAB=VA-VB                    “velocity of A with respect to B”

XAB=XA-XB                    “position of A with respect to B”

Meaning here we will be studying about the acceleration,velocity and position of one (A) object with respect to another (B) . Here B is acting as reference point for A. 
Or we can say our observer is at B point . 

   










tips & tricks 

HOW TO USE :

Take the Velocity of Our Observer (Here It Is B) and Make Its Direction Opposite, Like Rotate It to 180 Degree And “Add” It With The Velocity Of Object (Here It Is A)

NOW CHECK AGAIN THE PREVIOUS EXAMPLE WITH THE ABOVE METHOD
