Hello All,
Explain the pushes, pulls, movement, friction and gravity used in the game.
The marble needs to be pushed by the hockey stick, but not too much otherwise it will go off the paper. The hockey stick is pulled back so that the marble can be hit. There is very little friction between the hockey stick and the marble and that is why it can be hit so easily. Also there is very little friction between the paper and marble so it doesn't need much of a push to roll. The gravity is pulling down on the marble and so that is why it stays on the paper most of the time. Sometimes the marble goes in the air as the hockey stick lifts it up, but the gravity pulls it back down so that it will land again.


Cheers Tania
