what are vectors? who says the correct ans i'll mark as brainliest answer
Answers
Step-by-step explanation:
vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. ... Two examples of vectors are those that represent force and velocity.
Answer:Vectors
This is a vector:
vector
A vector has magnitude (size) and direction:
vector magnitude and direction
The length of the line shows its magnitude and the arrowhead points in the direction.
We can add two vectors by joining them head-to-tail:
vector add a+b
And it doesn't matter which order we add them, we get the same result:
vector add b+a
Example: A plane is flying along, pointing North, but there is a wind coming from the North-West.
vector airplane, propellor and wind
The two vectors (the velocity caused by the propeller, and the velocity of the wind) result in a slightly slower ground speed heading a little East of North.
If you watched the plane from the ground it would seem to be slipping sideways a little.
vector airplane ahead and slightly sideways
Have you ever seen that happen? Maybe you have seen birds struggling against a strong wind that seem to fly sideways. Vectors help explain that.
Velocity, acceleration, force and many other things are vectors.
Subtracting
We can also subtract one vector from another:
first we reverse the direction of the vector we want to subtract,
then add them as usual:
vector subtract a-b = a + (-b)
a − b
Notation
A vector is often written in bold, like a or b.
A vector can also be written as the letters
of its head and tail with an arrow above it, like this: vector notation a=AB, head, tail
