Question

Unlike velocity, speed is scalar, which means it is described by ______
only.

Answer 1

Hi there,

Unlike velocity,speed is scalar,which means it is described by MAGNITUDE only.

Answer 2

magnitude

Step-by-step explanation:

There are two types of quantities.

Scalars: The quantities which are completely described by their magnitudes only are called scalars.

For example, mass, length, time, speed, temperature, etc.

Vectors: The quantities which are completely explained by their magnitude and direction both are called vectors. For example, velocity, weight, force, momentum, etc.

As speed is a scalar quantity so it can be completely described by their magnitude only.
