What is speed a scalar or vector quantity?

scalar


Is length a scalar or vector?

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


Which are the scalar quantities?

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.

Is hours a vector or scalar quantity?

Since you can represent that with a single number, it isn't a vector - just a scalar.


Is a 100 yard dash a scalar or vector quantity?

Scalar because you give only the distance, not direction as well. It would also be scalar if you had quoted only the speed (not velocity), for the same reason. A vector has magnitude and direction.
