HP Cycle 28

🟢 6: F 2/26, 🔵 8: M 3/1 conservation of energy, K & Ug

Today, we will talk about mechanical energy, including kinetic energy and gravitational potential energy. Finally, we'll explore the conservation of mechanical energy.

Presentation: Work & Energy Presentation (we will try to get through slides 23-35 today)

Optional Extra Practice: Page 2 in Work & Energy Packet. (Unit 6 CompuSheets Answers)

🟩 6: M 3/1, 🟦 8: T 3/2 ↩️ Pivot lab energy conservation

Today, we'll check our understanding of energy conservation by doing a lab in ↩️ Pivot Interactives called "Height vs Velocity for a Puck on a Ramp." Our goal in this lab is to find an experiment model for the relationship between the release height and the final velocity for an object sliding down a frictionless ramp. We'll compare this model with a theoretical model based on the concept of conservation of energy. We'll also use our data to find an experimental value of the acceleration due to gravity.

Homework: ↩️ Pivot Interactives lab "Height vs Velocity for a Puck on a Ramp" is due on Thursday at 10pm.
