Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

2. Which of the following is/are true of angular momentum?

a) torque is time derivative of angular momentum

b) angular momentum is conserved in a system that has no losses (like friction)

c) angular momentum is a vector quantity

d) a-c are all correct

Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
