Forces

Force
example 

Say like your in a car and going in a pool you cant open the door half way because the forces of the water is pushing the door shut but when you  go all the way down you can because the car door and the water is equal.

Push  

Push is when you push someone or push a button it involves fingers and hands pushing someone involves strength Pushing is hard to learn when your little but when you get older its not so bad when you push it it rolls away 

Pull

It is when you Shove something or someone  it will come towards you if you pull it hard it will come too you fast if its slow it will come too you slow

friction 

when you walk the friction moves you forwards so u can go fast when you walk

gravity 

Gravity is on the centre of earth so when we walk we wont float if we didn't have gravity we wouldn't know how to learn we would learn to going space and die 

air Resistance

when the marble goes town the tube the air will make it Go down and go on the next thing

potential energy 

Its when the potential makes the marble stay where  it is so it doesn't move when you don't release it it stays on the spot 

Kinetic energy 

When you release the marble the kinetic  makes the marble roll on the spiral thing and makes it go faster 

Balanced  force 

Balanced force is where the object is even it it wasn't even the weight wouldn't be even and one would go higher then the other one

Unbalanced force 

When the object goes the unbalanced  force makes the ball go up and down like its jumping and when it goes down the connectors  it will jump because the unbalanced  force isn't balanced ed with the ball .

accelerate

say the ball is roiling the ball will start getting faster that why the accelerate is making it go fast then it will slow down because it will go on another track .

motion 

the motion moves the marble to go and do the work for you it wont stop moving until the motion and all the forces stop on it .
