PHYSICS [1 Mark Question Answer]

Velocity, since it is mentioning the direction of motion along with its speed.

As the car is brought back to its starting point, the displacement is zero.

A physical quantity that needs both magnitude and direction to be described is called a vector quantity.
Examples : Displacement, velocity, acceleration, force and weight.

When an object as a whole moves to and fro about its mean position, it is said to be in oscillatory motion.
Examples : a swing in motion, a moving pendulum, etc.

Speed does not depend upon direction so it is a scalar quantity whereas velocity depends upon the direction of displacement so it is a vector quantity.

An object is said to be in motion if it changes its position with respect to a certain fixed reference point in its surroundings.
