MECHANICS : FORCES - Vectors and Scalars
In vector subtraction, the vector that is subtracted is reversed in direction and then:
Ignored.
Divided by the first vector.
Multiplied with the first vector.
Added to the first vector.
Which of the following describes the addition of two vectors A and B along the x and y axes?
The sum of the components of A and B along the x-axis is the x-component of the resultant vector.
Both A and B should be perpendicular.
Both A and B should be of equal magnitude.
The sum of the components of A and B along the y-axis is the y-component of the resultant vector.
The result of adding two vectors is called:
Dot product.
Scalar product.
Vector sum.
Cross product.
Which of these quantities has both magnitude and direction?
Displacement.
Time.
Distance.
Speed.
The direction of the vector resulting from a cross product is determined by:
The left-hand rule.
The right-hand rule.
The angle between the vectors.
The magnitude of the vectors.
