Lilly being a spy!!! her mission: get past the evil motion detectors!

Today in labs we used motion detectors to learn about velocity acceleration and speed. we did experiments where we had to match the line given to us and see what kinds of moments would make it go up and down or stay the same. it was very interesting. i was a little confused about why the velocity went down even when i stoped, but then i figured out that it was going down because i wasnt moving or speeding up. acceleration is a another word for speed so when you speed up you acceleration line goes up and when you slow down the line goes down with you. it was all very interesting.
