Distance vs. Displacement

Distance is the total traveled.     .                  .
                                                             distance


Displacement is the distance between the start position and the end position.

Barbie Bungee Data Estimates

I think that the drop distance would be 163cm if we hand 10 rubber bands. If we had 20 rubber bands the drop distance would be about 207cm. If we had 30 rubber bands i think that the drop distance would be around 350cm. I estimated     the drop distance see the data that we got when we had 8 rubber bands. And jest by comparing the data we  got and the jest estimate the drop distance.

Metric Units

    I think we use metric in science class instead of english units because is easier to measure with.

         Things that has metric units...
                           
                                          -the refrigerator 
                                          -the stove
                                          -the table
                                          -the doors

Estimating Distance

    My estimate of the length of the front of my house is about 7.5 meter.

1. I had to see how many feet are in a meter

2. Measured the sidewalk planks

1 meter=100cm                 1 meter is going to be 3 ruler +10cm

ruler=30cm                 

In front of my house there are 5 blocks and every block = to 5 feet...

5 x 5 =25            30 x 25 =750            7.5

                                           

         I think that this is a reasonable estimate because the front of my house is not the big , so yeah.                                  

Reaction Time

     Reaction time is the way you react and how fast you react. 
When i'm playing soccer and they pass me the ball my reaction have to be fast , because if i don't react fast somebody  else is going to take it away from me, you do not want that to happen. When you are drinking very hot coffee and is about to fall you better react fast to that because that really burns and you have to react smartly because if you react stupidly you might spill some more. When you are distracted and someone calls your name and you look and a baseball ball is coming directly to your face you have to react quickly if you don't want the ball to hit you.
