Objective: Find what's the relationship between position and time.
Procedure: Our plan is to time how long it takes for the buggy to travel in intervals of 50 centimeters ending at 300. we will use our phones as timers and a meter stick to measure the distance. for trial 2 we will add a 500 gram weight to the buggy and conduct the same experiment as trial 1.

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 10.067cm. might want to round these

VM: As the position increases, the time increases proportionaly
MM: Position=(50.094cm/sec)time + 6.9cm
Slope: For every one second, the buggy travels 50.094cm
Y-Intercept: when the time is 0 seconds, the position is 6.9cm
Claims/Evidence: The slope shows the velocity of the buggy. the y intercept showed where the buggy started. the buggy should have the same velocity because all of the buggys are similar.
Conclusion: I conclude that the buggy traveled at a constant speed. We saw that the slope of both our trial 1 and 2 were proportional because the trend line was linear. more evidence to support that the buggy is at a constant speed, is that we added weight to the buggy and the trend line was still linear. some errors in our lab could have been reaction time because our y intercepts were not 0. i liked this lab because we got to experiment with the buggies and see how fast they went. i also liked that we got to learn new terms like displacement and velocity. it was a god intro to physics for me. good job! Just use proper capitalization - it's a formal report. ;)
