Slopes+and+Rollers

=** Slopes and Rollers **=



Aim: Our aim is to prove Newton's 1st Law. We want to find out how long a marble will continue rolling at different angled slopes.

Thesis: We think that with a higher angled slope, the marble will roll further than with a lower angled slope.

Materials:
 * Wood 60cm (x2)
 * Wood 9cm (x11)
 * Wood 18cm (x6)
 * Half a cardboard tube (x1)
 * Glue gun (x1)
 * Measuring tape (x1)
 * Marble (x1)



Process: Throughout the process of the experiment, we changed the design of the experiment a lot. We started off with a complicated idea of how to build the slope, we after a while realized that we could make it a LOT more simple. We spent a while building the experiment and improving it. Soon we finished and started with the actual experiment.

Method:


 * 1) First of all, set up the experiment, put the slope in position and roll out the measuring tape.
 * 2) Place the tube at the first level (6cm)
 * 3) Without applying any force, let the marble roll down the slope
 * 4) Measure how far the marble rolled
 * 5) Repeat steps 2-4 putting the tube a level higher each time
 * 6) Be sure you wrote down the results!

Result: Our theory was proven correct. The lower slope didn't manage to get the marble further, the distance the marble rolled increased when the slope was adjusted higher. On the highest level, the marble bounced when it hit the floor, but this didn't cause it to roll less.
