Unit 3 Free Particle Model (Balanced Forces)

• Newton's First Law (9:41) - Discussion of inertia and Newt's First Law. Includes some demos from class. (alternate link)
• Quickcast - Intro to Forces (7:08) - Screencast lecture covering the First Rule of Forces and naming forces.
• Quickcast - Types of Forces 1 (7:02) - Quick video defining some different types of contact forces and the direction the push/pull.
• Quickcast - Types of Forces 2 (6:22) - More types of forces shown and defined. We also start using our full agent object force notation.
• Interacting Force Diagrams (9:26) - What happens when you have more than one object?
• System Schema (21:03) - How System Schema can help us identify interactions (forces) between objects.
• Quick Cast - Force Components (6:37) - Just a quick look at components of forces.
• 2D Force Diagrams (14:55) - In this video we look at identifying types and magnitudes of forces on a ramp and then we introduce the idea of vector components.
• Lecture Capture - Videos captured during lecture
• Introduction to Force Diagrams (7:17) - This was our first look at how to draw force diagrams and how to properly label our force vectors.
• Force pairs (12:12) - When one box sits on top of another box they push on each other. How do those forces compare?
• Old Stuff:
  
• Interacting Forces (9:27) - Quick walkthrough of force diagrams on hanging masses, including an introduction to the idea of systems.
• Quick Equilibrium Problem (5:04) - Just a short walk-through of an equilibrium problem. (alternate link)
• Forces on a Ramp (14:04) - A ball on a ramp showing the resultant acceleration when weight and normal force are added together. (alternate link)
• Ramp Lab Expectations (5:36) - This is exactly what I'm looking for. (alternate link)
• Friction Home Lab - This is a video I made a couple years ago. I obviously didn't do very well, so you'll have to turn up your volume to hear it.
• Another Look at Inclined Planes (8:17)- Force on a ramp with an alternate coordinate system. (alternate link)

• Introduction to Projectile Motion (16:32) - As the title says. This introduces the concept of projectiles and the independence of horizontal and vertical motion. (alternate link)
• Projectile Math Part 1 (21:16) - Math with projectiles launched horizontally.
• Half Projectile (13:00) - Just a quick half projectile problem and the answering of an age old question.
• Introduction to Circular Motion () - Quick coverage of the concept of Circular Motion. Circular Motion math will be in a future video.
