Question

A physical quantity which cannot be negative is
A. Displacement
B. Velocity
C. Acceleration
D. Distance

Answer 1

Hint: Let us first get some idea about the physical quantity. A physical quantity is a material or system property that can be measured and quantified. A value is the algebraic multiplication of a numerical value and a unit to express a physical quantity. The physical quantity mass, for example, can be expressed as n kg, where n denotes the numerical value and kg denotes the unit. At least two qualities are shared by all physical quantities. The first is numerical magnitude, and the second is the unit of measurement.

Complete step-by-step solution:
Let us know about each an every option one by one
Displacement: The position of an object changes as it moves relative to a reference frame (for example, when a lecturer moves to the right of a white board or when a passenger moves toward the back of an aeroplane). Displacement is the term for this shift in position. The term "displacement" refers to the movement or displacement of an object.
Velocity: The rate of change of an object's position with regard to a frame of reference is called velocity, and it is a function of time. Velocity is a physical vector quantity that requires both magnitude and direction to define.
Acceleration: The rate of change of an object's velocity with respect to time is called acceleration in mechanics. Accelerations are quantities that are measured in vectors (in that they have magnitude and direction). The orientation of the net force acting on an object determines the orientation of its acceleration.
Distance: The term "distance" refers to the amount of space between two objects. Distance is a term that relates to the physical space between two objects, such as the distance between your parking spot and the mall's entrance. It can also refer to a period of time, such as the two years since you graduated.
Distance, speed, and other scalar quantities cannot be negative. Distance is the only parameter that cannot have a negative value. The amount of time it takes to reach a certain distance will never decrease. The travelled distance is a scalar quantity with no direction.

Note:Let us get some idea about Scalar quantity. A scalar is a quantity with magnitude but no direction. Physical quantity symbols are usually a single letter from the Latin or Greek alphabet, and they are printed in italic style.
