Today we will spend some time on Newton's Third Law. It's easy to misunderstand this principle, so we'll do an experiment which should make things clear.
Most real-life situations involving forces suffer from a complication: friction, which acts to hinder one object from sliding across another. Fortunately, we can use a simple model of friction to calculate its effects to reasonable accuracy.
Since friction problems often involve objects moving on tilted surfaces, it's important to know the key approach to setting up such problems.
If we have time, we'll look at this complication; if not, you might read it yourself, as it will help with a homework problem.
