Week 12: April 28 - May 2 Universal Gravity

Goals:
1. Be able to describe what gravity is.
2. Be able to use and explain the equation for the law of universal gravitation: F = m*m/d2. (I'm unable to write superscripts and subscripts here. The equation is saying that the force due to gravitybetween two objects is proportional to the product of the two masses divided by the distance between them squared.)
3. Be able to support the law of universal gravitation with graphs.

Activities:
Monday: Go over Quiz. Notes on Gravity
Tuesday: Work time on Gravity problems in class
Thursday: Film: Zero G. Practice Problems.
Friday: Review. Quiz. Notebook.

Notebook Contents:
1. Notes on Gravity
2. Gravity Questions
3. Video Nots: Zero G
4. Gravity Practice Problems

Week 11 Circular Motion: 4/21-25

1. Be able to describe what force is necessary to keep an object moving in a circular path.
2. Be able to explain the difference between the real centripetal force and the imaginary centrifugal force.
3. Be able to apply Newton's Laws to circular motion.
4. Be able to explain how an object stays in orbit and what factors must work together to make it happen.

Monday: I was sick. Eureka videos.
Tuesday: Go over returned work. Attempt to explain the motion of a bucket of water as it spun over my head using Newton's Laws.
Thursday: Illustrate and annotate one of three options about circular motion. Present illustrations. Homework: Orbits worksheet.
Friday: Go over homework. Review. Catch up. Quiz.

Notebook:
1. Notes from Tuesday on circular motion.
2. Orbits Worksheet

Weeks 9 and 10: April 7 - 18

Sorry for the missed weeks

Goals:
1. Know that all objects fall with the same acceleration in the absence of air resistance.
2. Be able to explain why all objects fall with the same acceleration in the absence of air resistance.
3. Use the concepts of air resistance and net force to explain why objects reach a terminal velocity.

Activities:
Monday, April 7: Go over returned work. Collect data about falling objects with the motion detector.
Tuesday: Continue explanation about the acceleration due to gravity and do the activity Ernesto's acceleration.
Thursday: Terminal Velocity lab with coffee filters.
Monday April 14: Go over results of Terminal Velocity Lab
Tuesday: Work on review question packet.
Thursday: Review activity and Game
Friday: Forces Unit Test (material covered:In general be able to state and apply Newton's three laws of motion. Some specifics: calculating net force, calculating acceleration due to one or several forces, describing the effects of forces, explaining the motion of pushed,thrown and dropped objects in terms of forces and inertia, differentiating between mass and weight, calculating weight, explaining why all objects fall with the same acceleration, explaining how terminal velocity is reached, describing the nature of forces as an interaction, describing action and reaction forces, differentiating action and reaction forces from balanced forces. whew.)

Notebook:
1. Ernesto's Acceleration
2. Air resistance, Terminal Velocity and Coffee Filters
3. Graph
4. Checking your Understanding Questions.
