You saw many new quantities in learning about motion. Make a list of all the different quantities you have observed and write yourself a brief description along with the symbol(s) for each quantity. In particular, note which quantities are vectors and which quantities are scalars. What laws and definitions connect the quantities you learned about?
2.Representations.
As you explored motion, you used a variety of representations. Make a list of these representations and their important features. What do you find advantageous about each representation? What were the limitations of each representation?
3.Sensemaking.
If physics is going to describe the world you live in, it should make sense in the context of your everyday experiences. Make a list of the strategies you have for making sense of physics contexts, systems, equations, and more. Your list can have more than just the things you have learned about in this course. As you make your list, think about the strengths and weaknesses of the different strategies. What do you think will be especially useful for you going forward?
4.Explore - Marbles.
You throw three marbles off the same table, each with the same initial speed but a different initial direction, as shown in the figure below. The floor in front of the marbles is flat.
Make predictions for each of the following. For each prediction, give a supporting explanation.
Which marble do you think will travel the farthest from the table?
Which marble do you think will be in the air for the most time before it hits the floor?
Which marble do you think will have the greatest speed right before hitting the floor?
