It is only angular momentum which has both direction and magnitude.

Sorabh said: (Jan 19, 2014)  
Angular momentum = M.I * Angular velocity and angular velocity is vector quantity.

Heat is scalar but temperature is vector.

Fon. L said: (Sep 25, 2015)  
Temperature is not a vector.

Why not work?

Kavya said: (Apr 29, 2016)  
Work is defined as a dot product (or scalar product) of force and displacement, both of which are vectors.
A scalar product of two vectors gives a scalar result.

dW= Fs cos theta

Where F & s are the magnitude of the vectors.
(Theta being the angle between the vectors).

Someone please clear me to know easily about the scalar and vector quantities.

If a quantity can have magnitude and direction to determine as well as is called a vector.

If a quantity can have magnitude and unit to determine As well as is called scalar.

On another hand. If two quantities contain the dot product between them then the 3rd. The quantity which is determined by these two is scaler and. If contain cross product then it is called a vector.
