A vector is a quantity with magnitude and ___?
A vector is described by magnitude and direction (a scalar has only magnitude).
Is A vector is a quantity that is fully described by magnitude alone?
No, a vector is a quantity that is fully described by both magnitude and direction. Magnitude represents the size or amount of the vector, while direction indicates the orientation of the vector in space.
A physical quantity described by both magnitude and direction is called what?
A physical quantity described by both magnitude and direction is called a vector. Vectors are commonly represented by an arrow pointing in a specific direction, with the length of the arrow representing the magnitude of the quantity.
What is the name given to the physical quantity which can be completely described by specifying both magnitude and direction?
The physical quantity that can be completely described by specifying both magnitude and direction is called a vector. Vectors are represented by arrows, where the length represents the magnitude and the direction represents the direction.
What is Vector quantity?
A vector quantity is a physical quantity that has both magnitude and direction. Examples include velocity, force, and acceleration. Vectors are represented by arrows, where the length of the arrow represents the magnitude of the quantity and the direction of the arrow indicates the direction of the quantity.
A vector quantity has direction a scalar quantity does not true or false?
True. A vector quantity has both magnitude and direction, while a scalar quantity only has magnitude.
How does a vector quantity differ from a scalar quantity?
A scalar quantity defines only magnitude, while a vector quantity defines both a magnitude and direction.
Can you graphically represent a vector which has magnitude but no direction?
If a quantity does not have a direction, its a scalar quantity, not a vector quantity.
What two pieces of information are necessary in order to define a vector quantity?
To define a vector quantity, you need both magnitude (size or length) and direction. For example, in physics, velocity is a vector quantity that requires both the speed (magnitude) and the direction in which an object is moving to be fully described.
Is magnitude a vector?
No, magnitude is not a vector. Magnitude refers to the size or quantity of a vector, but it does not have direction like a vector does.
Is the position scalar or vector quantity?
Position is a vector quantity as it has both magnitude (distance) and direction in space.
Why do we say that velocity is a vector and speed is not a vector?
Velocity is a vector because it has both magnitude (speed) and direction. Speed, on the other hand, is a scalar quantity that only has magnitude. Vector quantities require both magnitude and direction to be fully described.
