Questions and Answers

Why is the displacement zero when a car travels 10 miles North and 10 miles South?

The North and South displacements are vector quantities with opposite directions, canceling each other out (correct)

The car's acceleration was zero in both directions, resulting in zero displacement

The North and South displacements are scalar quantities with opposite values, canceling each other out

The car's speed was constant in both directions, resulting in zero displacement

What is a key difference between vector addition and scalar addition?

Vector addition follows the distributive property, while scalar addition does not

Vectors have both magnitude and direction, while scalars only have magnitude (correct)

Vector addition is simpler than scalar addition

Vector addition is commutative, while scalar addition is not

Study Notes

Displacement and Vector Addition

The displacement is zero when a car travels 10 miles North and 10 miles South because the two displacements are equal in magnitude and opposite in direction, resulting in a net displacement of zero.
A key difference between vector addition and scalar addition is that vector addition takes into account both the magnitude and direction of the vectors, whereas scalar addition only considers the magnitude.

Law of Vector Addition

The Parallelogram Law of Vector Addition states that the total displacement can be found by completing the triangle formed by the vectors.

Properties of Vector Addition

Vector addition is not done algebraically because vectors have both magnitude and direction, making it necessary to use geometric methods to add them.
The commutative property, which is not applicable to scalar addition, distinguishes vector addition from scalar addition, meaning that the order of the vectors being added does not change the result.
