Velocity is a measure of both an object's speed and its what?
Direction. Velocity is a vector quantity. Vectors have a scalar size and a vector direction.
Something that must be described with both a size and a direction?
A vector quantity (velocity, etc.)
When we subtract a velocity vector from another velocity vector the result is?
Still another velocity vector (or a zero vector).
Which is vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Which is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
What is a quantity that is specified by size and direction?
. Velocity Acceleration

What are properties of a vector quantity?
A vector quantity not only has a size, it also has a direction. Velocity is a vector quantity. "30 mph north" and "30 mph east" are different velocities. "Speed" is a part of velocity ... its size alone, without its direction, so speed is not a vector quantity.

Still another velocity vector (or a zero vector).
Can a particle in one dimensional motion have less speed than velocity?
Speed and velocity cannot be compared because they are different things. It is like saying "apples > oranges". Velocity is a vector and, as such, it has a direction and a size. The size of the vector velocity is it's speed.To answer your question: no because they can't be compared. And if you wanted to ask if the size of the velocity vector being smaller than the speed... no... that is the definition of speed... so it cannot be different, regardless of the number of dimensions you are using.
Which is vector speed or velocity?
"Speed" is a scalar; "velocity" is a vector.
Is moment a vector or a scalar?
A vector. Since velocity is a vector, moment, which is mass x velocity, is also a vector.
Which is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Is a vector quantity speed or velocity?
velocity is a vector and speed is a scalar.
Why angular velocity is vector quantity?
Because it's a type of velocity and velocity is vector quantity
Is angular velocity a vector quantity?
Yes, angular velocity is a vector quantity
