We can model and understand many simple systems with just Newton’s Laws. However, to solve some problems we need to add additional information to work out how a system will start to move or change when forces are applied to it. In this chapter, we look at conservation laws for energy and momentum. Like Newton’s Laws, these are fundamental principles about how the world works, now backed up by centuries of observation.
The two we focus on in this chapter are the conservation of linear momentum and conservation of energy. Our experiments will explore motion of ball bearings constrained in various ways. We need to explain what these two quantities are, and how we measure and keep track of them.
We start ...
