Details of Steps in Rube Goldberg

Step 13:the dominos then hit the green ball into the cup trapping it. Energy Transfer: newton's 2nd law.
Step 12:the train car then hits the dominos.Energy Transfer: newton's 2nd law.
Step11:the train car goes down the ramp(hill).Energy Transfer: Potential to Kinetic,Incline plane. Acceleration of train car determined by a=m/F.
Step 10:the ruler then trrigers another train car.Energy Transfer: Potential to Kinetic, Incline plane.
Step 9:the weight drops down on a ruler(cut yard stick).Energy Transfer: Lever
Step 8:the ball then triggers a weight. Energy Transfer: pulley
Step 7:the new golf ball goes down a ramp(half pipe).Energy Transfer: Potential to Kinetic,Incline plane.
Step 6:the train car hits another golf ball.Energy Transfer: newton's 2nd law.
Step 5:The ball then hits the train car.Energy Transfer: newton's 2nd law. Speed of train car determined by speed and mass of car relative to mass of ball.
Step 4:The ball then goes through the tunnel(pringle can).Energy Transfer: Potential to Kinetic,Incline plane.
Step 3:the ball goes down the half pipe.Energy Transfer: Potential to Kinetic,Incline plane.
Step 2:The ball goes down the blue slide.Energy Transfer: Potential to Kinetic,Incline plane.
Step 1:The golf ball goes through the hole in the orange circle.Energy Transfer: Potential to Kinetic,Incline plane.
