Question

which one of the following is not a vector quantity velocity acceleration speed momentum​

Answer 1

Answer:

Speed

Explanation:

Speed is a scalar quantity because it has only direction no magnitude. Hope it helps

Answer 2

Among velocity, acceleration, speed and momentum, speed is not a vector quantity, because to describe speed there is no requirement of direction.

$\rule{190}{1}$

Additional Information

Scalar Quantity

Those physical quantities which depend on only magnitude is called scalar quantity.

Vector Quantity

Those physical quantities which depend on magnitude as well as direction is called vector quantity.

Velocity

The change in position or displacement divided by the time interval is called velocity.

Acceleration

The rate of change of velocity is called acceleration.

Speed

The distance covered by moving body in unit time is called speed of the body.

Momentum

The product of mass and velocity of body at given time is called the momentum of body at that time.
