Question

Which of the following statements about vectors and scalars are true? List all that apply.

a) Vectors have magnitude and direction
b) Scalars have only magnitude
c) Speed is a vector quantity
d) Displacement is a scalar quantity

Answer 1

Vectors have magnitude and direction, while scalars have only magnitude.

Step-by-step explanation:

A vector is any quantity that has magnitude and direction. It is represented by an arrow, where the length of the arrow represents the magnitude and the arrowhead indicates the direction. A scalar, on the other hand, is a quantity that only has magnitude, without any direction.

Based on this information, the correct options are:

• a) Vectors have magnitude and direction
• b) Scalars have only magnitude
