1. Preliminaries

Question 1

How can you obtain the momentum of an extended material object that occupies a region of space?

Answer 1

Break it up into infinitesimal pieces of mass, dm and determine the momentum of these pieces
- The sum together the momentums to get the total (integrate)

Question 2

What is the moment of the momentum called?

Answer 2

The angular momentum

Question 3

What is the conservation of linear momentum?

Answer 3

The rate of change of total momentum must equal the total external unbalanced force on the object

Question 4

What is the conservation of angular momentum?

Answer 4

The rate of change of angular momentum must be equal to the net torque on a body

Question 5

What is the rule for dimensional analysis?

Answer 5

The dimension of a product of physical quantities is the product of the dimensions of the individual multiplicands

Question 6

What are tensors?

Answer 6

A generalization of vectors which have more than 3 components in 3 directions

Question 7

What are tensors of rank 0 and rank 1?

Answer 7

Rank 0 - Scalars
Rank 1 - Vectors
