Proficiency #5

My 5th proficiency was with dominoes. i was using Newtons Laws Of Motion. i am using the law that an object in motion stays in motion until acted on by an outside force. Well i set up the dominoes but in between to i put a tissue and i put a car. i timed how long it took for the snowball effect to end so i did it   3 times i did one with car and tissue. And 3 times without anything.

Tissue
1-1.15s
2-.60s
3-.58

car
1-stopped
2-(moved closer) stopped
3-(closer) stopeed

None
1-.30
2-.23
3-.16
As you can tell Newtons Laws did work it either slowed it down or stop it completely.
