THERMAL ENERGY

Part 4

MONDAY, 2.11.2019

• 1. Pick up a Motion Energy Games worksheet.
• 2. Today’s Plan
• This week’s agenda
• Cheer celebration
• Momentum games

MOMENTUM ACTIVITIES

• Choose two activities to fill out on the worksheet.

GT MONDAY, 2.11.2019

1. Continue working on your Project Momentum build. 2. As you build, check in with me for advice. 3. You can start testing when you are ready, but we will do the official rubric test together.

Category Points Description Reliability 20 Device must be able to work 20 times without repair. 1 point per cycle. Variable Mass 5 The mass of the propelled device must be easily changed. Variable Force 5 The force of the propulsion must be easily changed. Distance Consistency 10 Device must be able to launch the same mass with the same force10 times with a variability of less than 10 percent. Scalability 10 Distance should be approximately double when force is doubled or mass is halved. Usability 10 Operation should be self-explanatory and simple. Mass and force should be stable for multiple launches. A user should easily be able to identify relative force for each launch.

TUESDAY, 2.12.2019

• 1. Turn in your Thermal Quiz Rework!
• 2. Make sure you have a fresh focused notes page.
• 3. Get out your Motion Energy Games worksheet.
• 4. Today’s Plan
• Momentum notes.
• Discuss motion games.

MOMENTUM NOTES

• Momentum is the measure of an object’s kinetic energy.
• Momentum is the product of mass * velocity.
• An object can transfer all or part of its momentum.

𝑁𝑝𝑛𝑓𝑜𝑢𝑣𝑛 𝑞 = 𝑛𝑏𝑡𝑡 𝑛 ∗ 𝑤𝑓𝑚𝑝𝑑𝑗𝑢𝑧 𝑤 → 𝑞 = 𝑛 ∗ 𝑤 TPS: Does an object need to be moving to have momentum?

MOMENTUM UNITS

• You don’t have to memorize units.
• The equation can tell us what the units are.

𝑁𝑝𝑛𝑓𝑜𝑢𝑣𝑛 𝑞 = 𝑛𝑏𝑡𝑡 𝑛 ∗ 𝑤𝑓𝑚𝑝𝑑𝑗𝑢𝑧 𝑤 → 𝑞 = 𝑛 ∗ 𝑤

• Mass measured in kilograms(kg)
• Velocity measured in meters pers second(m/s)

𝑛𝑏𝑡𝑡 𝑛 ∗ 𝑤𝑓𝑚𝑝𝑑𝑗𝑢𝑧 𝑤 → 𝑙𝑕 ∗ 𝑛/𝑡

• The unit we use for momentum is kg*m/s

• Energy transfer is very similar to bowling.

DOMINOES

• Group Share

a) When you set them up, you are storing potential energy between the top and bottom of the domino. b) When you set tip them, you release the potential energy and the momentum knocks over the next domino.

1. Continue working on your Project Momentum build. 2. As you build, check in with me for advice. 3. You can start testing when you are ready, but we will do the official rubric test together.

WEDNESDAY, 2.12.2019

• 1. Pick up a Graphing Basics Notes sheet.
• 2. Talk to your elbow partner to answer the question:

“Why do we use graphs?”

• 1. Today’s plan:
• Graphing basics: https://www.youtube.com/watch?v=ssXPrG0PGDY
• Momentum Graphing Lab Part 1.

WHY DO WE GRAPH?

• As the saying goes, a picture says a thousand words.

Over the course of a school year, we observed the relationship between students who took notes and their grades. We discovered a relationship between the two variables. For students who took less than 1 page of notes a week, their grade was not affected positively or negatively. Grades began to improve for students who took more than one page of notes a week. Students who took more than three pages of notes every week showed significant improvement in grades.
