Class this week: Finishing our study of Newton's laws with several online resources and an activity using spring scales, blocks, and sandpaper. Get ready for a test next week.
Table of Contents for Forces Unit (digital copies of all items!) Resources for Forces Unit HW = Homework WU = Warm Ups Monday, 10/15 HW: WU: No written warm up, silent reading today. Tuesday, 10/16 HW: Finish front of Forces graphic organizer. See above post below this one for instructions. See Table of Contents for the graphic organizer paper (but any paper will do!). WU: 1.Write down Newton’s third law. 2.Draw two arrows representing balanced forces. 3.Draw two arrows representing Unbalanced forces. Wednesday, 10/17 HW: Test next Wednesday, 10/24, Forces. WU: 1.What is the relationship between force and motion described by Newton’s first law? (D44) 2.What is inertia? How is the inertia of an object related to its mass? (D46) 3.INFER: Once a baseball has been hit into the air, what forces are acting upon it? How can you tell that any forces are acting upon the ball? (D42) Thursday, 10/18 HW: Forces test next Wednesday, 10/24 WU: 1.What are some everyday examples that show that friction increases because surfaces press together with greater force? 2.What are some everyday examples that show that friction decreases because the texture of the surfaces changes? 3.If you are trying to slide a chair across the floor, how does increasing the weight in the chair influence the force you need to slide it? Friday, 10/19 HW: Finish Newton's Laws Graphic Organizer. See above post for more instructions. Forces test Wednesday, 10/24. WU: 1.Summarize Newton’s second law in a few brief words or phrases. 2.Which equation goes with Newton’s second law? 3.What happens to the force if you increase the mass, acceleration, or both? 4.What force keeps an object moving in a circle? In what direction does this force act? Comments are closed.
