What else can I help you with?
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.
A quantity that expresses magnitude but does not express direction?
Scalar. Scalars are quantities in physics that are fully described by their magnitude alone and do not have a direction associated with them. Examples of scalars include temperature, mass, and speed.
The direction and speed of an object is described by its?
The direction and speed of an object is described by its velocity, which is a vector quantity that includes both magnitude and direction.
What quantity is completely described by magnitude alone?
Scalar quantity is completely described by magnitude alone, without any direction. Examples include temperature, speed, and mass.
What additional information for velocity is needed that isn't needed for speed?
To fully describe velocity, you need both the speed (magnitude) and the direction of motion. Speed, on the other hand, only requires the magnitude of the motion, regardless of direction.

In velocity do you put the direction?
No, velocity includes both the speed and direction of an object's motion. It is a vector quantity, which means it has magnitude and direction. So, when stating the velocity of an object, both the speed and the direction must be included to fully describe its motion.
The quantity that expresses magnitude but does not express direction is?
Scalar. Scalars are quantities that are described by magnitude only, without any direction. Examples include distance, speed, and temperature.
Wind is a vector quantity because it has what two attributes?
Wind is a vector quantity because it has both magnitude (speed) and direction. These two attributes are needed to fully describe wind as it moves in a specific direction at a specific speed.
Is a scalar just magnitude?
Yes, a scalar is a quantity that has only magnitude and no direction. Scalars are described solely by their size or magnitude. Examples include temperature, mass, and speed.
A velocity vector tells you two things?
Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.Speed (which is a magnitude), and the direction.
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.
What describes an object's velocity with a direction?
An object's velocity with direction is described by its speed and the direction of its motion. Velocity is a vector quantity that includes both magnitude (speed) and direction, providing information on how fast and in which direction an object is moving.
