week 3 blog post

What we did in Monday's Lab: talked about how can we support play that is exciting but not dangerous but this time in the lab we primarily focused on the question of what affects a rider's speed down a slide? By table group, we ended up putting this question to the test where we designed and conducted our own investigation where we also were to support everything with evidence when we could as well. I took away and learned that,

What could affect variables of speed down a slide:

- rider weight, slide material, rider clothing, initial force of push. for our investigation we decided to focus on slide material.

- our question was how does the material of a slide change the speed of a rider? we found that the smoother the material the faster the object would move. The materials we used were wood, plastic, foil, and ceran wrap. This was an interesting investigation that proved that different materials affect a riders speed.

What we did in Thursday's Lecture: In the lecture today, we again reviewed some of the variables people looked at and considered from the lab's investigation about what affects speed. I had a good reminder that acceleration equals change in velocity over time.

Questions about Weekly Textbook Readings:

1. What did you learn? I learned more information on force and motion. A force is a push or a pull that moves an object. Friction and Resistance are two big concepts related to force and speed. Friction and resistance will end up slowing down objects over time.

2. What was most helpful? The concept of Newton's First Law was one of the most important parts because I had a refreshed memory about what that all was because I had forgotten. In the press book reading, Newton's First Law was described as representing objects at rest remaining at rest, while objects in motion stay in motion unless acted on by an unbalanced force. I thought that was a really good reminder and an important concept that I do not always think about so I thought that was helpful overall to improve my overall science knowledge topics.

3. What do you want more information on? The concepts of inertia are something that I know basic information about and the stuff from the press book reading, but what all makes up inertia, and how important is inertia in science really?

4. What questions/comments/concerns do you have? Are there any objects that never stop moving? How is this possible when friction and resistance are still a thing?
