How does spacing between dominoes affect the average velocity of the dominoes? Increasing space between each domino will decrease its velocity, decreasing the space will increase its velocity. Force at which it hits next dominoes is increased it will take longer for it hit, acceleration is constant, the longer it has to travel, the longer it will take to hit.
According to Newton’s first law every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it. This relates to the domino effect since the nothing can happen until the first domino hits the second one and continues in such a pattern. Due to the conservation of energy, the law of conservation of energy states that energy may neither be created nor destroyed. Therefore the sum of all the energies in the system is a constant….f one domino fails to reach other there is no force acting upon and therefore will cease. Also Newton’s second law relates to the velocity aspect of the research question: Newton's Second Law of Motion: The relationship between an object's mass (m), its acceleration (a), and the applied force (F) is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector. A force causes only a change in velocity (an acceleration). According to Newton an object with a certain velocity maintains that velocity unless a force acts on it to cause acceleration (that is, a change in the velocity). This applies to the experiment because the further is has to travel the greater the average velocity.
Independent: distance between dominos, force applied,
Controls: the amount of dominos used, the size of the dominos, facing same direction, position of dominos (vertical) for selected tests, forced applied
Materials: Dominos, stop watch, ruler, desk, carpet.
