    and their average velocity and prove the theory about the relationship between the mass of an object and the average velocity. This was done by using different numbers of coffee filters and analysing the data of the curved graph using the GO-Motion detector. In table 1‚ we can clearly see that the higher the mass of an object is‚ the higher the average velocity is. If we have one coffee filter with the mass of 1.26 grams‚ the average velocity is -.506 m/s‚ and if we have 5 coffee filters with the
