Forces and Motion:Marble run

At the top of the marble run Kinetic Energy and Gravity is posed on the marble At the gate, Then as you Push the piece that is in front  of the marble. Once you have Pushed  the piece the marble will go down and on to the ''S'' obstacle but then that is when Motion comes in as it goes down the marble meets the swirly obstacle. Air resistance comes in to slow the marble down.....

Mass vs weight, What is the difference between Mass and Weight 

Mass is measured in kilograms or pounds. A one-liter volume of water has a mass of one kilogram. Weight is measured in newtons, the standard unit for force. A one-kilogram mass placed on a bench presses down on the bench with almost ten newtons of force.
