Can sum of two vectors be numeric?
No, the sum of two vectors cannot be a scalar.
Can the resultant of two vectors be 0 how is it possible for two vectors always?
If they are equal in magnitude but act in opposite directions.
On earth weight vectors always point toward?
Center of the earth
Why the product of two vectors is sometime scalar and sometime vector?
Because there are two different ways of computing the product of two vectors, one of which yields a scalar quantity while the other yields a vector quantity.This isn't a "sometimes" thing: the dot product of two vectors is always scalar, while the cross product of two vectors is always a vector.
Compound subjects always consist of two simple subjects?
Not always
When vectors are added or subtracted what is the net force called?
The sum of vectors is not always a force. It might be a displacement, a velocity, acceleration, momentum, divergence, curl, gradient, etc. In any case, the algebraic combination of several individual vectors is the "resultant".
What is the relationship between force vectors and free body diagrams?
E=mc^2 to the negative 100. bottomline is force vectors are free body diagrams always sometimes
Is the endpoint of a ray always the second of two letters used to name the ray?
True when the rays represent vectors. Not always true otherwise. This is partly because with vectors ab is not the same as ba whereas with ordinary lines such a distinction is not important. False
Can be magnitude of a vector have negative value?
Vectors have magnitude and direction. The magnitude is always a positive number.
What are vectors and what are the 2 properties of them?
Vectors are quantities that have a value as well as a direction.Vector addition is commutative: x + y = y + xThe value of the sum of two vectors is always less than or equal to the sum of their individual values.|x + y| ≤ |x| + |y|
What does a solar system consist of?
It consist of dust, gas, always one star, and possibly planets--like ours!
When would gravity be a vector?
The forces between two masses that arise as the result of gravity are always vectors.
