Class this week:
We are working on our unit on forces and Newton's Laws. We will use a computer simulation to manipulate forces, mass, and friction to calculate net force. We will do a lab using spring scales, blocks, weights, and sand paper. Test on forces and Newton's laws will be on Friday, 10/18. Table of Contents: FORCES - These papers should currently be organized in your binder! Resources and online textbook: FORCES HW = Homework WU = Warm Ups Lost your Warm Up Sheet? No problem. Print one here. Warm Up Sheet Next Quiz or Test: Friday, 10/18, Forces Test. Monday, 10/14 - We did a lab today! Static and Dynamic Friction Lab with Spring Scales HW: Study for test on Friday, 10/18. WU: 1.If two people push a heavy box in the same direction, each with a force of 20 N, and friction from the floor is a force of 10 N, then what is the net force on the box? DRAW it out! 2.What happens when you push a chair across the room with a medium force and then a stronger force? 3.What instrument could we use to measure Newtons of force? Tuesday, 10/15 HW: Study for test on Friday, 10/18. WU: 1.What is centripetal force? Give an example. 2.Give examples of real situations with balanced and unbalanced forces. 3.If you push a 20 kg box with an acceleration of 2 m/s2, what is the force you used? F=ma Wednesday, 10/16 HW: Study for test on Friday, 10/18. WU: 1.You shove a shopping cart down the aisle of the store. It has a mass of 18 kg and an acceleration of 3 m/s2. What force did you use? (F = ma) 2.If a car makes a sudden stop, what happens to a passenger in the back seat who is wearing a seatbelt? What law is this? 3.List the following objects in order from least to most inertia: large rock, feather, pencil, textbook. Thursday, 10/17 HW: Study for test on Friday, 10/18.
