RUBE GOLDBERG PROJECT POST
STEPS:
A – Step A involves a 45 gram golf ball rolling down a slope. After the ramp the golf ball then reaches a small track that it runs along until it bumps into a flexible platform that a bouncy ball rests on.
B – After step A the force from the golf ball hitting the platform. Knocks the bouncy ball into the main part of the course.
C – Next the bouncy ball goes through a series of tracks constructed of popsicles until it reaches step D
D – Following step C the bouncy ball will tap a small popsicle stick with a golf ball resting on it, the force from the bouncy ball rolling down the track will generate enough power to tap the golf ball off of the courses edge.
E – For the final step the golf ball activated by the bouncy ball then proceed to fall of the edge and fall through 3 ribs keeping the golf ball in place. Until it reaches the bottom and lands on a switch.
ENERGY TRANSFERS
1. The first type of energy transfer we see is Potential to Kinetic, this is shown when the golf ball rolls down the ramp and onto the track from a stand still position.
2. The second energy transfer is Kinetic to Kinetic. In the video shows the ball stalling between a gap in 2 popsicles sticks before continuing to roll through the rest of the course. This energy transfer is shown as Kinetic to Kinetic due to the ball briefly pausing before continue.
3. The last energy transfer is Kinetic to Sound. When the golf ball falls and hits the switch which makes the flick sound.
