Question

ans this plz .......

Answer 1

Velocity is the displacement travelled by a body per unit time. It is a vector quantity as it contains both magnitude and direction.



Passengers tend to fall because of Inertia of Direction.

Answer 2

1. 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 thus it is a vector quantity.
2. Passengers tend to fall sideways due to INERTIA according to which a body resists any change in state of it's motion and in the given situation the direction of motion is changed.
