Step 1: Pull Wedge Wedge – Object separating, lifting, or holding objects in place Force of marble against wedge – 0.0029 Newtons

Step 2: Marble 1 hits Marble 2 Marble 1 hits Marble 2 and transfers its kinetic energy to Marble 2 Kinetic energy of 0.0021 Joules

Order Steps 3-7 and Steps 8-10 happen simultaneously

Step 3: Marble 1 Falls Through Funnel Marble 1 accelerates due to gravity Falls with a force of 0.44 Newtons

Step 4: Marble 1 Through Screw Screw – Mechanism that converts rotational motion to linear motion Force of marble decreases by 1.5 meters per second

Step 5: Inclined Plane Inclined Plane – Flat surface tilted at angle to reduce force required to do work Used to guide marble to hit dominoes

Step:6 Dominoes Toppling – When center of gravity of extends outside area of support Each domino transfers its kinetic energy to the next domino

Step 7: Dominoes Hit Catapult Support Wooden pole supports catapults weight box (3.725 kilograms) Requires 0.5 Newtons to topple support

Step 8: Marble 2 Rolls Down Track Velocity of 0.3 meters per second

Step 9: Marble Switchback Potential energy to kinetic energy transfer Velocity of 0.76 meters per second Kinetic energy of 0.14 Joules

Step 10: Marble Drop To Catapult Potential energy to kinetic energy transfer Initial velocity of 0.53 meters per second Velocity in air of 1.27 meters per second Final velocity of 1.8 meters per second

Step 11: Catapult (Lever) Launch Lever – Rigid object with fulcrum that multiplies input force Marble launched with a force of 1.54 Netwons

Step 12: Funnel Catches Marble Used funnel to catch various marble flight paths

Step 13: Hits Button Button releases car Marble hits button with a force of 0.45 Newtons

Step 14: Car Drives Down Track Car drives with a force of 0.08 N

Step 15: Car Hits Wood (Which Hits Mass) Car hits wood and an equal force is applied to the mass Kinetic energy of car transferred into kinetic energy of wood Required force to move mass is 0.1 Newtons

Step 16: Pulley Pulley – Wheel attached to axle designed to use a belt across its circumference Pulley = holding mass with potential energy of 2.15 J (theoretical kinetic energy when released)

Step 17: Egg Cracked Purpose of machine – Crush/crack egg Hits egg with an impulse of 1.5 Kilogram meters per second
