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.

Lilly's beach house (with no beach) on the moon.

Lilly has decided to move to the moon for he summer and visit her house there. she is very excited becuase she recently had a swimming pool installed. she is wondering what the difference will be when she jumps in to a swimming pool on the moon and jumps in a swiming pool on the earth so she asks her magical cat to explaine it to her.
her cat siad " since the moon has a smaller gravitaionaly pull then the earth you will not fall as fast. but when you hit the water you wont go into the water very far you might actualy go back up into the air because of the boyancy pullng you upwards but once you are out of the water again you will fall bag down and the same thing will happen agian".
"Gee thanks" said lilly "i am sure i will have a great time"
