Lab: 

During  this week similar to the week before we tested out different variables and their effects that they have on swings. My group decided to test out whether or not wait has an effect on a writer's swing ability. And similarly to our last trial of weight and slides, we concluded that there is not a big connection between a writer’s weight and how many times the swing goes back-and-forth or how fast it goes back-and-forth. One thing that I found difficult during this week's lab was figuring out how to test out whether or not wait really affects the swing.

This week in class, we began to focus on new playground equipment, which is the swing. We also began to discuss force in a different effect It has on objects. More specifically we talked about doing first the second law and how they relate to and explain force. During lecture, we also discuss the effects of gravity and what it has on a rider during sliding, but more specifically swinging this week. For example, we learned that the force of gravity is always pulling down on people and the force of either a swing or a rope is always pushing against them. We also talked about how motion is affected by gravity and force which is why swings are able to move back-and-forth.

Focus questions:

1. What did you learn?

• Inertia, before reading this chapter, I didn’t really have a full understanding of what she was exactly but as able to learn the definition, but also the importance it has within new laws. 

2. What was most helpful?

• The videos and simulations helped me gain a better understanding of how force work sensitive different aspects there are that affect it. it also gives a more hands on learning approach to the topic.

3. What do you need more information on?

• I think that the last section of the article could use some more information or examples of how objects are able to move without being touched.

4. What questions/concerns/comments do you have?

• One question I have from the reading is related to the fact that the force needs to act on an object that is not in motion in order to make it move. Is it possible to increase the force on an object if it is already in motion? For example, if you’re playing with a tether volleyball and it’s already spinning around and you hit it again does this mean that force is adding to the original force used to start the ball motion.
