Car P is heading east with a speed V and car Q is heading north with a speed . What is the velocity of car Q with respect to car P?
It is a vector quantity. A vector quantity is a quantity having both magnitude and direction. Speed is a scalar quantity and it is a quantity having a magnitude only. Motion in a plane is also known as motion in two dimensions.
The equations of motion in a straight line are:
v=u+at
s=ut+½ at2
v2-u2=2as
Where,
