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

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.
