High Impact

Pull: 
We didn't use the force pull in our marble as much as you could, the force pull means you're pulling something towards you. Without pull we couldn't get things to us or move a object for your self for someone else. e.g my mum asked me if I could help her pull the mattress to the other side of the room where we were. 


Air Resistance: 
This force is what slows something down while being in the air! Which means that you won't be going to fast down in the air. e.g I went sky diving the other day and I didn't go down towards the ground quite fast, because of the Molecules in Air Resistance.


Balanced Forces:
Balanced forces mean that a object that is moving will keep moving in that same motion and a object that is completely still will say that way. Our marble run did exactly that, our pieces/course stay completely still to hold our marble while its constantly moving down the track!! 


Motion: 
Is a simple force which means that objects are moving all the time in motion. e.g our marble stayed in Motion while on our marble run track. Without motion there would be no sort of thing as movement. Without Motion we don't have any movement which would make things worthless.
