Scalar quantities are physical quantities that have only magnitude and no direction. Examples include mass, temperature, speed, and volume. These quantities are described fully by their magnitude alone.
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.
Torque is a vector quantity because it has both magnitude (how strong the force is) and direction (the axis about which the force is applied).
