Question

Out of mass, velocity, momentum and force, which one is not a vector quantityOut of mass, velocity, momentum and force, which one is not a vector quantity​

Answer 1

Answer:

ANSWER

Vector defined with a magnitude as well as direction.

Exp:- Displacement, Velocity, Momentum, Force, Torque.

Scalar have only magnitude but not direction.

Exp:- Mass, Distance, speed and energy

Option A

please mark me as branliest

Answer 2

Mass is not a vector quantity.

• A scalar quantity has magnitude only, whereas vector quantity has both direction and magnitude.
• Now, there are four physical quantities mentioned in the question -

1. Mass
2. Velocity
3. Momentum
4. Force

• Among the given physical quantities, velocity, momentum and force, can have both magnitude and direction. So, all of them are vector quantities for sure.
• But, mass (a fundamental quantity) has only magnitude. It's impossible (and illogical also) to determine the direction of mass. Hence, we can conclude that mass is a scalar quantity, (or, mass is not a vector quantity).
