Problem:Does the amount of dominoes effect its over
allspeed and acceleration?
Hypothesis:I believe that the more dominoes, the greaterthe speed. I think this because the moredominoes, the more force, and with more
force,the faster the dominoes will travel.

1. Gather all Materials2. Line up 5 dominoes,
separated evenly 3. Measure the distance
from domino 1 to the last domino
4. Start the timer5. Time until the last
domino falls
6. Record data7. find speed (distance
divided by time)8. Repeat steps 2-7 two
times add 5 dominoes each time
9. Record all data
IV: DominoesDV: SpeedCV: Spaced evenly, same distance apart,
same surface, same timer, same dominoes

Problem: Does the surface of the ramp effect the speedof the ball and how fast it falls?Hypothesis: I think that the surface will change the speed of theball, because different surfaces cause a differentamount of friction. I think that the trash bag-coveredramp will have the fastest time. I think this because thetrash bag isn't clinging, like the smooth surface, and itisn't ruff like the towel. I predict that the towel will havethe slowest time because of its ridges and its rufftexture. I also think that the faster the ball rolls downthe ramp, the faster gravity will pull it to the ground.
1 tote lid 1 large tote 1 small tote 1 trash bag 1 tennis ball Tape Towel Flexible sled for smooth texture 2 timers
Gather all materials set up both totes Position tote at desired angle Tape trash bag to tote Roll the ball Time its roll Time its fall of the edge(for seed of gravity) Recode data Repeat 5-8 Repeat 5-8 Remove trash bag Tape towel Repeat 5-8 (3 times) Remove towel Tape sled(smooth surface) Repeat step 13
