Forces, Pressure, and Friction

This lecture is an introduction to forces and a review of Newton's Laws of Motion, with a particular focus on his 2nd Law.

This lecture reviews various types of forces and how to draw free-body diagrams to understand how forces act on objects.

This lecture combines free-body diagrams and Newton's 2nd Law using formulas and calculations to solve problems.

This lecture covers the idea of pressure created by solid objects.
