2.6

1. What would happen if there are equal forces pushing on opposite sides of a ball? Draw a picture, showing the forces as arrows pointing toward the ball.

2. What would happen if there was a large force pushing a ball from the left, but only half of that force pushing the same ball from the right at the same time? Draw and explain.

2.8

1. (2 pts) If there is more than 1 vector, how do we find the result?

2. (8 pts) Draw the vectors on your paper. Draw the resultant and calculate its magnitude and direction.

4E, 2N, 4W, 4S

2.12

1. Imagine an airplane flying at altitude. Diagram and label all forces acting on the airplane.

2. Imagine a fat cat lounging on top of a backpack. Diagram the cat and label all forces acting on the cat.

2.14

1. What is inertia?2. Give 2 real world examples that

demonstrate the 2 parts of Newton’s 1st Law.

Magazines! Yay!Step 1: Look through a magazine either alone or with 1

partner, and find 1 article that is interesting to you (at least a little)

Step 2: Write down the answers to these questions on a piece of lined paper-What is the main topic?-What is the author’s main argument?-What data does the author use to prove his/her argument?-What is your opinion on this article?/Why is it interesting?

Step 3: Write 1-2 paragraphs (5-10 sentences) about the article that you find most interesting. Use the answers to the questions to help you form your paragraph.

Step 4: Share your article with the class verbally
