∙ 6y agoA VECTOR has both direction and magnitude.
If a measurement has only direction, is just the direction.
If it has magnitude (usually distance or force) but NO direction, it is described as SCALAR.
For example, consider a ship cruising across the ocean.
Case a) If its speed is 20knots, then we have only its speed, and speed is scalar.
Case b) If it is moving at 20kt due Eastwards, then its course is a vector, by specifying both its speed and its direction.
Strictly speaking, in Case a) we are right to say "speed" but in Case b), we can say "velocity" because velocity is the vector of speed and direction.
So, a vector is not direction alone, but is direction with speed or force: you need to quote the values of both.

What vector is created by pointing in a particular direction?
Which of the following are not vector directions?
What is the difference between resultant and equilibrant vector?
Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.
Which of the following are not vector directions. 35 degrees inside 35 degrees north of east north outside 45 degrees?
None are as they do not properly describe a vector. A vector must have a direction and velocity.
Is force a vector quantity if so why?
Yes, force is a vector quantity, because it is exerted in a specific direction (even in the case of a symmetrical explosion, in which force is exerted in all directions, that is still a type of vector).
Can a single vector be replaced by two vectors in the x and y directions.?
For most purposes, yes.

What the difference between vector and resultant vector?
Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.
Explain how a swarm of flying insects can have a net momentum of zero?
If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.If they fly in different directions, the momentum (which is a vector quantity) of the individual insects can cancel.
What is the difference between resultant and equilibrant vector?
Equilibrant vector is the opposite of resultant vector, they act in opposite directions to balance each other.
If the component of vector A along the direction of vector B is zero. What can you conclude about these two vectors?
Their directions are perpendicular.
A physical quantity that has both magnitude and directions is?
Such a physical quantity is a vector.
What mathematical operation do you do when two vectors point in opposite directions?
You do vector addition.
What is the vector sum of 7 and 5 and 13 and -5?
The whole point of a vector is that it has a magnitude and a direction. There are no directions given in the above string of numbers.
Which of the following are not vector directions. 35 degrees inside 35 degrees north of east north outside 45 degrees?
None are as they do not properly describe a vector. A vector must have a direction and velocity.

How to find the direction of vector when the magnitude is given?
You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions. You need some additional information to make conclusions about the direction.You can't derive the direction only from the magnitude. A vector with the same magnitude can have different directions.

Does directions matter when you are measuring momentum?
Yes, momentum is a vector variable and direction matters in vectors.
