What is the numerical value of a physical quantity?

Correct option is D

The correct answer is (d) Magnitude.

• The numerical value of a physical quantity is referred to as its magnitude.
• Magnitude represents the size or quantity of the physical parameter being measured, without considering its direction.
• It is a scalar quantity, meaning it only has magnitude and no direction, as opposed to vector quantities, which have both magnitude and direction.
• For example, the magnitude of a force could be 10 Newtons, indicating the strength of the force without specifying the direction in which it is applied.

Information Booster:

Magnitude:

• Refers to the numerical value or size of a quantity.
• Used in various contexts, such as force, velocity, or electric charge, to describe how much of the quantity is present.
• Magnitude is crucial in both scalar and vector quantities, although in vectors, it is combined with direction.

Reference:

• A fixed point or standard used for comparison or measurement.

Direction:

• Indicates the line along which something moves or points, commonly associated with vectors.

Distance:

• Refers to the total path length traveled by an object, which is a scalar quantity.
