Demo - Vertical Acceleration - Heavy vs Light. I demonstrate with a big force scale what happens to the tension in a string when I accelerate a mass up and down. The positive accelerations create more tension, and the negative, less. I then review the different positive and negative accelerations:
Positive is you start to go up, or you go faster and faster up, but it could be when you stop going down, or go slower and slower as you move down.
Negative is you start to go down, or you go faster and faster down, but it could be when you stop going up, or go slower and slower as you move up.

Demo - Force of Friction. I use a Vernier force probe, and gradually increase the force on a block of wood with 2 kg resting on it. Usually you get this perfect graph (practice making it) of static and kinetic friction. (Check the image in the folder at the top of the page) You can talk about the difference between static and kinetic friction - how there are weak molecular bonds that break and can't form when the object is moving. This relates to anti lock brakes, and also traction control that cars have today. Also XC skiing, but literally nobody XC skiis. Sigh.
Lab - Force Table - The Website lays it out pretty well:
Lab - Race tracks. A simple game using graph paper that simulates Newton's First and Second laws in a race.

Lab - Friction Lab. Standard stuff. We do it for general Physics.

Demo - Patty's Bricks. I sing them the song after they have suffered through all of those force word problems.
