A vector is the mathematical representation of an action or other entity that has both magnitude and direction. One of the most common contrasts is that between speed, which has magnitude but not direction, and velocity, which also has direction. A speed of 60 mph has the same meaning in any direction, but a velocity of 60 mph north has significantly different consequences from a velocity of 60 mph south, especially if one begins from some point on the north shore of a lake!

Why speed is scalar while velocity is vector?
Speed is scalar (that is, without direction) and velocity is a vector (speed plus direction) by definition in physics.
What is negative vector in physics?
That's a vector whose direction is exactly opposite to the direction that you designated as the positive one when the exercise or analysis began.
A quantity that requires both magnitude and direction?
I had this question in my physics class as well and the answer is vector :)
What is useful of vectors in physics?
vector is important because it shows direction as well as magnitude
Is amount of substance a vector or scalar quantity?
In physics, "vector" usually means that a direction is relevant. If you just have a number, as in "number of moles", then a direction is NOT relevant.
What is unit vector in physics?
a vector having unit magnitude and have a certain direction.
What is position vector in physics?
A position vector tells us the position of an object with reference to the origin
Physics notes of class xi?
resultant vector a vector in which 1 side shiner and another side is polish is called resultant vector
What has the author T N Lockyer written?
T. N. Lockyer has written: 'Vector particle physics' -- subject(s): Mathematical models, Particles (Nuclear physics), Vector analysis
Is it true that all physical quantity which has a direction and a magnitude is a vector?
I think so, yes; that's basically what the concept of a "vector" in physics is all about. (There are also more abstract vectors in math and physics, but something that has a magnitude and a direction would be enough to quality as a vector.)
When drawing a vector using the triangle method of addition how do you draw in the resultant vector?
When drawing a vector using the triangle method you will draw in the resultant vector using Pythagorean theorem. This is taught in physics.
Is a vector diagram needed to solve all physics problems properly?
False
Why speed is scalar while velocity is vector?
Speed is scalar (that is, without direction) and velocity is a vector (speed plus direction) by definition in physics.
What is negative vector in physics?
That's a vector whose direction is exactly opposite to the direction that you designated as the positive one when the exercise or analysis began.
Is velocity speed?
As used in physics, the two are different. Speed is a scalar, velocity a vector.
What does an over-line bar over a variable mean in physics?
It could represent a vector.
A quantity that requires both magnitude and direction?
I had this question in my physics class as well and the answer is vector :)
