A positive acceleration happened in three places of the Rube Goldberg machine. The first was located at the beginning when the first marbles slides down the shoe (inclined plane). Without enough force and acceleration the marble’s hit wouldn’t be enough to make the car move, too much force and acceleration the marble flies out of the shoe. The second instance is when the weight is added into the pulley system, the harder it falls into the cup going down the higher the other cup lands. The third instance is after the chain of dominoes collapse and send the marble rolling down the inclined plane. The speed of the changes the distance it will go, therefore it had to be the exact acceleration in order for it to land into the cup.

Negative Acceleration is shown when again in the pulley system whereby the string and force of the cup the second cup is pulled up as the same direction of the nvelocity. It then slows down showing two indications of a negative
