Which of the following is not a vector quantity?
A)Weight;
B)Nuclear spin;
C)Momentum;
D)Potential energy

Potential energy
In case of option D.
Given that it only has magnitude, potential energy is a scalar quantity. Since it doesn't rely on that, it lacks direction. The standard unit of potential energy is the joule. Hence, potential energy is a scalar quantity.Thus, option D is the correct option.Explanation for the incorrect answers:
In case of option A.
A force that an object experiences because of its mass is called weight. which has a magnitude and a direction and is a vector. Hence, option A is the incorrect option.In case of option B.
Nuclear spin is also a vector quantity.As it has both magnitude and direction.Thus, option B is the incorrect option.In case of option C.
As the result of multiplying a body's mass, a scalar quantity, by its velocity, a vector, momentum is a vector quantity.Thus, option C is the incorrect option.Thus, option D is the correct option.
