Scalars are quantities that have magnitude only; they are independent of direction. Conversely, vectors have both magnitude and direction.
A scalar quantity is any numeric value that has no spatial direction. So let's look at your four tests.
There are two types of quantities in Physics scalar and vector. The square of Scalar quantities are positive numbers. The term Scalar was used to denote size or scale not direction. Scalar numbers have direction referred to the attraction negative or repulsion positive.
For example potential energy is a scalar energy E = -mGM/r the negative sign on this scalar denotes gravitational attraction.
A quantity that describes magnitude only not about the direction is called scalar quantity.
Example Height of man is 5ft only explain magnitude or if we buy sugar we are only concerned about quantity of sugar 2kg ,3kg e.t.c not about the 3kg sugar in west direction😂
Scalar quantities are quantities that have magnitude only; they are independent of direction.
Physical quantity which has only magnitude is called scalar quantity. Examples:
time, mass, work, energy, electric current, power, electric charge, magnetic pole strength
Any measurement for which a direction is not relevant.
More specifically, a scalar is a measurement of a type where a direction is not relevant. When a direction is relevant, the measurement is called a vector.

A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant).A scalar quantity is a non-vector quantity.

Current is a scalar quantity, I= dq/dt.
True, a vector quantity has direction, and a scalar quantity does not.
