Why are Motion and Newton's Laws Important?
Engineers analyze motion to understand
how things operate under various chemical, physical, and mechanical
conditions. The understanding of motion can be used to predict on
objects motion in future situations.
Engineers use models to predict things such as
motion, fluid flow, lift on an airplane wing, movement of neutrons
in a nuclear reactor, deflection of beams or columns, etc.
Newton's laws are widely used and
a good first example of engineering models.
