QuestionUn vector tiene magnitud y dirección, mientras que un escalar solo tiene magnitud. ¿Cuál es la diferencia?
Studdy Solution
STEP 1
Assumptions1. A vector is a quantity that has both magnitude and direction. . A scalar is a quantity that has only magnitude, not direction.
STEP 2
Let's analyze each optiona. A vector quantity has magnitude and direction, and a scalar quantity only has magnitude. b. Vectors are large quantities while scalars are small quantities. c. A vector has only magnitude unlike scalars which need a direction. d. Vectors are measurable quantities while scalars are abstract.
STEP 3
Option a is correct because a vector is a quantity that has both magnitude and direction, while a scalar is a quantity that only has magnitude.
STEP 4
Option b is incorrect because the size of vectors and scalars is not related to their definition. A vector or scalar can represent any quantity, large or small.
STEP 5
Option c is incorrect because a vector has both magnitude and direction, not just magnitude. Scalars do not need a direction.
STEP 6
Option d is incorrect because both vectors and scalars are measurable. Scalars are not abstract.
So, the correct answer is option a A vector quantity has magnitude and direction, and a scalar quantity only has magnitude.
