Mosi Ramp Lab
Purpose:
The purpose of this lab is to find the acceleration of an object rolling down a ramp at different heights. We used an app to collect results called logger pro.
Independent/Dependent:
-Height of ramp(Independent)
-Acceleration(for given height(Dependent))
Steps/ Procedures:
First, we gathered all our materials.
Second, we set up our ramp and set up our logger pro.
Third, we recorded the time from when the ball was released to when it fell of the ramp.
Fourth, we made a table and graph by setting dots on our logger pro so we can get our results.
Table/Data:
The circles is a positive exponential for our position. The rectangles is our velocity over time graph which has a correlation of 0.9947. This means it was very close to being 100% linear or known as a straight line or consistent velocity. We also set the max of 400 for both our velocity and position( y-axis) and for time we set at 2 seconds(x-axis) since our final point was recorded at 1.925 seconds.
Equations:
Velocity Equation: V=X/T
6 Numerical Values:
T= 1.46s, X= 243 cm, X Velocity= 386.70cm/s
T= 0.33s, X= 1 cm, X Velocity= 62.04cm/s
T= 1.93s, X= 446 cm, X Velocity= 468. 89cm/s
T= 0.66s, X= 30 cm, X Velocity= 133.72cm/s
T= 1.73s, X= 353 cm, X Velocity= 449.67cm/s
T= 1.12s, X= 128 cm, X Velocity= 289.48cm/s
Conclusion:
The six numerical equations show that the object increases the distance away from the origin. X=Postition, X= Velocity,T=Time. Acceleration is the increase of speed. In a graph is represented when time goes on the speed increases. It the velocity before the acceleration comes. Our graph recorded 62.04cm/s for velocity.
