Question

Problem 1

Answer 1

Given information

Given the speedometer of a car and asked if it measures speed or velocity or both.

Step-by-step explanation

Step 1.

Scalars are physical quantities that can be completely described by a numerical value or a magnitude alone. Vectors are those physical quantities where the direction also is specified along with the magnitude.

The terms “velocity” and “speed” are often used interchangeably in ordinary language as both have the same units (m/s).
