Final answer:
Vectors have magnitude and direction, while scalars only have magnitude. Use the criteria of directionality, representation by a single number, and vector addition/subtraction rules to classify quantities. Temperature and height are scalars, while velocity is a vector.
Step-by-step explanation:
A vector is a physical quantity that has both magnitude and direction, such as velocity, force, and displacement. A scalar, on the other hand, is a physical quantity that has only magnitude, such as temperature, mass, and time.
To differentiate between vectors and scalars, we can consider the following criteria:
- Does the quantity have direction? If yes, it is a vector. If no, it is a scalar.
- Can the quantity be represented by a single number? If yes, it is a scalar. If it requires multiple numbers or components, it is a vector.
- Does the quantity follow the rules of vector addition and subtraction? If yes, it is a vector.
Now let's classify the items listed:
- Temperature: Scalar. Temperature does not have direction and can be represented by a single number.
- Height: Scalar. Height does not have direction and can be represented by a single number.
- Velocity: Vector. Velocity has both magnitude (speed) and direction (positive or negative).
Encourage the student to classify the remaining items using the criteria mentioned above and provide a brief explanation or justification for each classification.
