Position-Time graph:
x=-0.2166t^2-0.01724t+0.004578 Slope: the buggy travels 0.2166 meters away from the starting position every second Y-Intercept: the buggy starts at 0.004578 meters Velocity-Time Graph: Vx=-0.4433t-0.007562 Slope: the buggy accelerates by 0.4433 meters per second moving away from the starting point Y-Intercept: the initial velocity of the buggy is 0.007562 moving away from the start point |
Conclusion/Evaluation:
The purpose of this lab was to explore velocity in relationship to the direction and slope of movement of an object. When answering the question "how does time effect position" it was discovered that the direction and rate of travel of the buggy could be found from the equation of the buggy movement and velocity was also discovered. Velocity is the rate at which an object changes position and is dependent on the speed and direction of the buggy found in the position-time graph/equation. The slope in a velocity-time graph equation shows the buggy acceleration while the sign of the slope determines if it is moving towards the start point or away from it. The y-intercept on the velocity-time graph shows the buggy's original acceleration and the sign of the y-intercept determines if the starting acceleration is towards or away from the start point. However, we recognize that our data towards the end of the buggy travel period was possibly skewed by the inability to see the point on the buggy that we used to graph its motion after the front of the buggy passed the view of the camera. Our data is limited to only one view of the buggy because we only completed one trial of the experiment which could impact the general data. One improvement that could have been made from this observed weakness would be to chose a point on the buggy that is visible throughout the entire video as our graphing point.
