K'Nex® Down hill and up (vibrations) on a U track
Focus Questions
- What will happen if two Down Hill Thrill K'Nex® sets are joined at the bottom without the jump?
- How many times will the cars go back and forth before stopping? (vibrate)
- Will a car go more times if it has more mass/weight?
- Will it go back and forth faster if it starts higher or lower?
Procedure
Connect two tracks at the bottom so that they make a big "U" with the track.
Start a car at the top of one and count the number of times it passes the bottom.
Repeat the procedure adding mass/weight/washers or starting at different positions.
