Acceleration+Lab+Expectations

__ Pose Questions __ : How might acceleration of a marble differ on ramps with different slopes? Does the question posed require you to determine the acceleration on one or two slopes? __ Hypothesis __ : Explain what acceleration is and predict the relationship between the manipulated and responding variables. __ Design an Experiment __ : Step by step, tell how you will test your prediction in a way so others could repeat it. Draw your setup with dimensions. Include the slopes for the two ramps you setup and how you calculated it. __ Collecting and Interpreting Data __ : Explain what the acceleration of the marble down a ramp looks like. Explain how your measurements support this observation. Put your data in a table. Show your acceleration calculations. __ Drawing Conclusions __ : Tell how your results relate to your hypothesis.
 * Acceleration Lab **

(If you think you only have to record times for a marble to roll down the whole ramp, you better think again. Look at what is needed to calculate acceleration.)

This data table is only half of what you need to complete this lab. Think, what data is needed? Look at everything that is needed to calculate acceleration by looking at the formula. Does the question posed require you to determine the acceleration with one or two ramp heights?



Average Time = Add the trials and divide by the number of trials.

First and Second Meter Time Minus First Meter Time Equals Second Meter Time or 1st & 2nd Meter Time - 1st Meter Time = 2nd Meter Time

Remember the speed formula:

Slope = Rise/Run

If you were unable to apply the concept of acceleration to a marble rolling down a ramp, this picture summarizes what you need to do to complete this lab.
