Thrust Structures Experiment.

Motion Lab

1. We could connect the numbers because its the same variable, we would just need to plug it into movement.
2. You could just go the same speed the whole time (vilosity=speed and acceleration=change)
3. Different because the person would be changing postition and their speed would be speeding up too.
4. Because the sensitivity in the certain variables (vilosity is easy to change, but position isn't so its slower)
5. You could have a negative slope in position vs. time because you could walk towards the motion detector instead of away.

Robo Lab

Today I worked with Alice and Clara on the Robo Lab. Together we experimented with a robot to make it push a small Lego "rock" forward and up a ramp and completely stop before it fell off. It took several tries and we got very close but we couldn't make it stop on time before class was over. At the beginning we decided it would work best if we each made a different route for the same trip so we could try more ways faster. Although we did not finish, I believe that if we had more time, we could have completed our task.

Moon

If I were to play golf on the moon where the acceleration due to gravity is 1.6m/s^2 I would swing the club fairly easier than I would be able to on earth because there is less gravity to pull it in the opposite direction. The golf ball would probably also be able to go faster and farther because there will be more lift than gravity. This is because Newtons 3rd Law states that for every action there is an equal and opposite reaction, when I swing my club at the golf ball, it will continue to swing back because I forced it to move forward and it doesnt want to stop because the energy I used to propel it forward will be used to keep moving.

Recovery System

Today i worked with Kimmy and Kathryn. We started by designing a parachute and securing a sand bag to it using string, hole puncher, plastic bag, and hair dryer. We started by cutting up a big plastic bag because it was too big. We tied four strings from the bag to the weight. This created strength and an equal balance. When we tried it by filling it with hot air, it still fell pretty easily. So I came up with an idea to add a second parachute above the first like a bi-plane. All though we never got to try this, we think it wouldv'e worked because the air wouldv'e flown through the two flaps to create lift, and it would go up slower so that it wouldnt come down to fast because of Newton's 3rd law
