Investigating motion

Julia L.


In this project, we had to create a project on our own based on two things. Motion and force. My partner was Rebekah and we chose to do a project with cars and ramps. We created a stand that had nails along it so we could lay the board down on each nail and use it as a ramp. We used a toy car and would see how far it went at each height. We collected data for ten different heights.


My question was: How will different length ramps affect the distance a toy car will go?


For the project we needed a toy car, wooden boards, nails, tape measure, stopwatch, and a flat surface. We set up our experiment in the road and had all the materials out. We then did the tests and recorded our data.

Above is the data we collected. We did three tests for each distance and had to get all the measurements exactly right. We found out that the highest one is not the fastest. As it gets higher, the car just ends up falling to the ground because there's no place to build up speed. It barely has an angle after a while and is just a straight board. The 14.1 was the best in the end because it was the biggest angle you could create without it all crashing down.


I think that the reason the car went down to such a crash after we raised the board was because it had no time or angle to build its speed off of. There was barely an angle when it got that high and it prevented it from going very far. the front of the car would just end up hitting the ground and it would be more like dropping the car then actually racing it.
