Question

give any two properties of vector addition

Answer 1

Vectors completely describe an effect by using a number, or component, to describe each of an object’s attributes.

Vector addition means we combine the two effects such that we create a new effect where each of its attributes is a sum of each of the parent effect’s attributes.

For example, a force can be described by the attributes

Force in the X-direction.Force in the Y-direction.Force in the Z-direction.

When you add two forces, it turns out that the new force’s force in the X is equal to the sum of the parent force’s X forces. Same for Y and Z.
