Hypothesis- I predict the Halls Cart will move up wheb the weight gets to be to much.

Materials-
Tape
Rod
String
Paper Clip
Halls Cart
100g
Washers

First Test

Washers distance

3 17.5

Second Test

Washers speed
2 rest
4 slow
6 fast
Third Test

Conclusion- The Hall's Cart speeds up the more you put Washers on it.My Hypothesis wash almost correct because it did weigh the cart down.
