What else can I help you with?
Is speed a scalar quantity or vector quantity?
Speed is a scalar quantity because it has magnitude but not direction, velocity is a vector quantity because it has magnitude and direction.
Why is velocity a vector quantity?
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
Is the distance a vector or scalar quantity?
scalar direction is a vector quantity
What are vector quanity?
Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.Any quantity for which a direction is relevant.
Is distance a vector or scalar quantity?
Distance is a sclar quantity. A scalar quantity is a magnitude only. A vector has magnitude and direction. Distance AND direction is a vector quantity.
Do vectors have direction?
Yes, vectors must have the direction. Without direction, it is simply a scalar quantity.
What quantity has only size?
A vector represents quantity that only has size, or magnitude, without any specific direction.
Is speed a derived quantity?
Velocity is a derived quantity. Speed is velocity without direction. Velocity is derived from distance and time.
Why is velocity is a vector quantity and why speed is a scalar quantity?
Velocity is a vector quantity because it has both magnitude (speed) and direction. It includes information about how fast an object is moving and in what direction. Speed, on the other hand, is a scalar quantity because it only specifies the magnitude of the object's velocity without indicating direction.
What kind of quantity is speed an example of?
Speed is an example of a scalar quantity, as it only has magnitude (numerical value) without a specific direction.
What is the difference between vector and scalor quantity?
Vectors include information about their direction, and are incomplete without it. Examples are displacement, velocity, acceleration, momentum, magnetic field. (Velocity is speed with direction.) Scalars are complete without stating any direction. Examples are temperature, cost, mass, speed. (Speed is velocity without direction.)
Is the air temperature in a room a vector quantity?
No, air temperature is a scalar quantity because it has magnitude only and no direction associated with it. It is a measure of the average kinetic energy of particles in the air, without any specific direction.
