That brings us automatically to our next subject, the fact that part of mathematics was developped to describe real-world problems, and thus is the natural language of physics. Let us study this issue by looking at a number of examples.
Example 1.1:
Describe the motion of a particle under a constant force
Solution:
Example 1.2:
Discuss the equilibrium of forces in a spiders web.
