Forces, Pressure, and Friction

Force Lecture 1 - Newton's Laws

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

Force Lecture 2 - Free Body Diagrams

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

Force Lecture 3 - Net force

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

Pressure Lecture

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

Friction Lecture 1

This lecture introduces the concept of friction including static and kinetic friction, and how to solve some friction problems.

Friction Lecture 2

Continuing on with friction problem solving, including a skid problem (sliding without any forward force).
