Not always. The direction is only necessary if you're discussing
a distance vector, but you're usually not.
A vector quantity refers to a physical quantity that has both magnitude and direction. Some examples of vector quantities include velocity (speed and direction), force (magnitude and direction), and displacement (distance and direction).
A vector is something which has both magnitude and direction. Examples include velocity which is speed (magnitude) in a given direction. When written using orthogonal components vectors are written as a column of numbers in parentheses (a one-dimensional array).
Vectors are used whenever there is a measurement in which not only the magnitude is relevant, but also the direction. Typical uses of vectors include position, velocity, acceleration, force, torque, and others.
These are two different types of measurements. One is length or distance and the other is weight or mass. Please edit your question to include more context or details.
Any vector quantity does. Examples of vector quantities include but are not limited to . . . - Displacement - Velocity - Acceleration - Torque - Force - Electric field - Momentum - Poynting vector
Yes. If you leave out any of that information, then you leave the next person guessing.

Vector quantities include magnitude and direction.
Yes. A displacement is a vector. A vector is some sort of magnitude and a direction. Since 3 blocks is a magnitue(it is a distance) and east is a direction, the quantity is a vector, and therefore, a displacement. However, if you did not include a direction, the quantity is scalar, meaning it has magnitude, but no direction. Saying "Walk Three Blocks" could mean to walk three blocks in any direction. Not very useful. Hope this helps!
technically yes as height has the direction of upwards. and has magnitude.
Yes it does!
A vector is something which has both magnitude and direction. Examples include velocity which is speed (magnitude) in a given direction. When written using orthogonal components vectors are written as a column of numbers in parentheses (a one-dimensional array).
A scalar is a quantity that describes magnitude(size) only. It does not include direction. Examples: Distance (2 cm, 4km) Speed (50 km/h) Mass (3g, 45 kg) A vector is a quantity that describes both magnitude and direction. Examples: Displacement (6km north) Velocity (60 km/h east) Force (15N downward)
Such a quantity is called a vector. A shining example is velocity itself. velocity is the rate of change of displacement- the distance moved by particle in a specified direction. Since velocity = displacement/time taken = vector/scalar, Velocity thus has both a direction and a magnitude (magnitude = speed of particle) Another examples include quantities such as Force, acceleration, displacement
That's called a "scalar" quantity. Examples include temperature, speed, and energy.
A quantity that has both magnitude and direction often has an arrow drawn over the unit of measurement. This is known as a vector quantity, as opposed to a scalar quantity which has no direction.
"speed" or "velocity" (if you include a direction)
