The document outlines several experiments that will be conducted to study Newton's laws of motion and related concepts. It includes experiments using dominoes to study the relationship between speed and acceleration, as well as experiments using ramps covered with different materials to study the effect of friction on an object's speed. A problem is posed about how the number of dominoes affects speed and acceleration, and a hypothesis is presented. The materials, procedures, variables, and data collection steps are described for conducting this dominoes experiment. A second problem and hypothesis is presented about how surface material affects the speed of a ball rolling down a ramp. The materials and procedures are also outlined for this ramp experiment.

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

13. Problem:
Does the surface of the ramp effect the speed
of the ball and how fast it falls?
Hypothesis:
I think that the surface will change the speed of the
ball, because different surfaces cause a different
amount of friction. I think that the trash bag-covered
ramp will have the fastest time. I think this because the
trash bag isn't clinging, like the smooth surface, and it
isn't ruff like the towel. I predict that the towel will have
the slowest time because of its ridges and its ruff
texture. I also think that the faster the ball rolls down
the ramp, the faster gravity will pull it to the ground.
