Week 3 Blog

 1. The lab focused on the main question, "How can we support play that is exciting but not dangerous?" More specifically we focused on investigating the speed of riders going down a slide. My group chose to narrow our experiment to whether the wetness of the slide impacted the rider's speed. We designed our investigation and conducted several test runs to ensure our measurements were as accurate as possible. We concluded that riders are faster when the slide is wet. 

2. In the lecture we discussed force and friction, and how those components impact the speed of the rider. 

We mainly focused on how those two components are involved with slide steepness. It was very interesting to learn about the angle of gravity and how friction and gravity are related. Also, we learned how different materials and clothing of the rider impact how fast they are going and how much friction is involved. 

3. The reading discussed force and how things can move through inertia, kinetic friction, and static friction. The graphics were very helpful in learning how force, motion, friction, and acceleration are all correlated. The reading also went into depth on all of Newton's Laws and explained things in a manor that was clear and easy to follow.
