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.
