28.(Pg. [38]) What is meant by the momentum of a body?
29.(Pg. [38]) How do we ascertain the momentum?
30.(Pg. [38]) How may a light body have a greater momentum than one which is heavier?
31.(Pg. [38]) Why must we multiply the weight and velocity together in order to find the momentum?
32.(Pg. [39]) When we represent weight and velocity by numbers, what must we carefully observe?
33.(Pg. [39]) Why is it particularly important, to understand the nature of momentum?
34.(Pg. [39]) What is meant by reaction, and what is the rule respecting it?
35.(Pg. [39]) How is this exemplified by the ivory balls represented in [plate 1. fig. 3]?
36.(Pg. [40]) Explain the manner in which the six balls represented in [fig. 4], illustrate this fact.
37.(Pg. [40]) What must be the nature of bodies, in which the whole motion is communicated from one to the other?
