A scalar measurement is one that requires only one number. For example, my mass is 82 kg. BUT some measurements require more than one number to specify. For example, a force on me has both a magnitude and a direction. Such things are called "vectors." Speed is a scalar quantity. I am going 35 km/hr, but velocity is a vector, which requires a magnitude, which is the speed, AND a direction. So my speed is 35 km/hr, but my velocity is 35 km/hr east.
This is a measurement of count or quantity, indicating the number of apples present. It is not a measurement of weight, volume, or length.
Time is considered a scalar quantity because it does not have a direction associated with it. Scalar quantities only have magnitude, like a point on a number line. In contrast, vector quantities have both magnitude and direction.

Length is a scalar quantity. By definition, a vector quantity has both magnitude (ie. length) and direction. Length does not have direction, so it is not a vector. Length is a scalar quantity. Length is a scalar quantity. yes
The potential gradient is a vector quantity. It represents the rate of change of the scalar electric potential with respect to position in space.
It is a measurement that doesn't have direction, such as distance. A vector has direction

Scalar
No, it's a scalar measurement because it has magnitude only. A vector measurement has both a magnitude and a direction.

A scalar is a single quantity that is represented by just a magnitude, such as temperature or speed. A vector is a quantity that has both magnitude and direction, like force or velocity. Scalars can be thought of as a subset of vectors with zero direction component.
A vector quantity.
Any measurement for which only a magnitude is required, but not a direction. The opposite of a vector: a measurement for which a direction IS relevant.
A scalar quantity has magnitude but no direction. It is described only by its numerical value and unit of measurement. Scalars can be added, subtracted, and multiplied by a scalar value.
This is a measurement of count or quantity, indicating the number of apples present. It is not a measurement of weight, volume, or length.
A scalar is a quantity that has only magnitude and no direction. In terms of measurement, a scalar measure is a numerical value representing the size or magnitude of a physical quantity without specifying the direction. Examples of scalar measures include temperature, distance, and speed.
