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.


When we subtract a velocity vector from another velocity vector the result is?

The result of subtracting one velocity vector from another velocity vector is a new velocity vector. This new vector represents the difference in speed and direction between the two original velocity vectors.


What is a quantity that is specified by size and direction?

. Velocity Acceleration


Quantity that has a direction associated with it?

Vector. A vector is a quantity that has both magnitude (size) and direction. Examples of vectors include velocity, force, and displacement.


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.


What is the size of the of the velocity?

Velocity is a vector quantity that has both magnitude (speed) and direction. The size of velocity is its speed, which is the rate of change of displacement with respect to time. It is represented by a positive scalar value.


Is moment a vector or a scalar?

A vector. Since velocity is a vector, moment, which is mass x velocity, is also a vector.


What is a quantity that has a magnitude and direction?

A vector quantity


Why angular velocity is vector quantity?

Because it's a type of velocity and velocity is vector quantity


This is a quantity that has both size and direction?

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
