Collisions

Collisions

The Collision experiment is the 2nd Experiment our group was assigned, but this time the experiment had to be completely by us in other words we couldn't use ramps that were already made we had to design our own and here is a picture of what our Ramp should look like: **Aim:** Show that if an unbalanced force acts on an object it causes the object to Move. **My Thesis:** I think that if we use a ball with a mass of 100g (example) and a 20g (example) the ball with a mass of 100 g will push the lighter ball 3 or 4 meters away.

Materials:

 * Ramp
 * Marbles
 * Machine to fire the marbles down the ramp (fires the marbles using rubber bands)



This is a picture (not a perfect one but....) of the **__FINAL__** Experiment. What we are planning to do is to have a Horizontally placed column pulled backwards (it will have marks on it so that we can measure the force that we are applying to the force ) and we will saw 5mm into each mark so that the rubber band fits in and the measurements will be more accurate, On the other side of the Ramp we will be applying the same force to a different ball with less mass and have them collide against each other and we'll measure

Building
(Today we built the ramp and the Machine to fire the marbles down the ramp, We worked in groups of three (dividing the group into 2 groups). I worked on the Ramp with Elise and Faven while Carlos and Tom worked on the Machine to fire the marbles down the Ramp, and they had to redesign it because Niklas is sick and he had the plans for the Machine.

Firstly we measured the length and width of the wooden sticks, then we used the saw to saw to cut the pieces of wood. Our first idea was to saw through an extremely thick wooden stick and we were told to use thiner wooden sticks. Once we had finished cutting through the 2nd wooden stick which we thought was going to be enough (at first) but we then thought that we will need 2 more wooden stick to make the 2nd Ramp, so we sawed 2 other wooden sticks for the 2nd ramp. All four sticks are 30 CM tall and 1 CM wide.

After we had sawed through the last wooden stick we had to cut another stick which was a more circular stick. This stick like you can see on the picture will be put into holes (not glued or taped... ect.) but we will be able to take it out to put it into different holes to be able to put the results of our experiment into a graph ( in other words it will be easier to make a graph out of it), but I think that we will have to make 2m graphs because of the way we designed our experiment. We will have to make a Graph for the results of the different heights and we will have to make a Graph for the different forces applied to the pushes on the marbles, and the second part of both graphs will be the different masses of the marbles and balls used in the experiment.)
