Pre-Lab Notes:
- stays in straight line
- moves
- makes a noise
- has lights-headlights and antenna
- flowers
- wheels
- red
- forward
- keeps going
- two seats
Objective: The objective is to find the relationship between the position and the time.
Procedure: This lab is called the Buggy Lab. The equipment we needed was tape, the buggy car, and a yard stick. We than walked to the hallway and marked 300 Cm. We than put tape in increments of 50 from 0 to 300. My group than measured how far the car went with out weight (370 grams) on it measuring the time it hit at every increment of 50. After that we added 500 gram (870 grams in al
l) weight to the buggy and measured the time it hit at every increment of 50. This was the procedure of our lab.
Graph:
Trial 1
if rounding, it's 56
position=(55cm/sec)time + 10.067cm
Trial 2
position=( 50cm/sec)time + 6.9 cm
Tables:
VM: As the position increases, the time increases proportionally
MM: position=(55cm/sec)time + 10.067cm
Slope: For every 1 second the position increases by 55.75 cm.
Y-intercept: When the time is zero seconds the position 10.067 cm.
VM: As the position increases, the time increases proportionally
MM: position=( 50cm/sec)time + 6.9 cm
Slope: For every one second the position increases by 50cm.
y- int: When the time is zero seconds the position is 6.9 cm.
Observations/Claims: We made a few observations/claims in this lab. The slope of showed the velocity of the buggy. Another observation we made was that the y-intercept showed where the buggy started. The buggy should have had the same velocity because all the buggies were made the same. Therefore, they were all similar and should have same velocity.
Conclusions: In conclusion, the buggy traveled constantly according to our graphs. We noticed that the buggies both traveled at constant speeds in trial 1 and 2. Although they both traveled at a constant speed, the trial 2 buggy traveled at a lower pace but was still constant. More evidence to support the buggy was at a constant speed was that even when we added weight the buggy was moving in a constant speed. There was definitely a few errors. One of the errors was that the car often did not travel in a straight line. Therefore, causing the time to be a little off. Another error was that we might not have timed the 50 cm increments correctly.why not? how can you fix? Lastly, another error was the reaction time because our y intercepts were not zero cm. I really enjoyed this lab because it was extremely fun and we had to find the velocity of a electric buggy car. I also learned new scientific terms. good!
nice work!
