Force - a force is a push or pull - there are two forces acting on all objects: - gravitational force - normal force |

Contact Force most forces require contact between objects |

Sc7 (binary/octet-stream)
|
Non Contact Force - some forces act at a distance - they don't need contact eg: gravitatonal magnetic electrical |

Sc8 (binary/octet-stream)
|
Balanced Forces - when the forces acting on an object are balanced, the object will not change speed or direction |

Sc11 (binary/octet-stream)
|
Unbalanced Forces - If the forces acting on an object are unbalanced, the object will accelerate |

|
Forces and Acceleration In science, acceleration means to 'speed up', 'slow down' or 'change direction' |

Inertia Newton's first law: Inertia "objects will continue to do what they are doing until an unbalanced force acts on them" | - an object moving at a constant speed/direction has constant velocity (balanced forces) - it will continue that unless an additional force acts on it |
Vector diagrams vector diagrams state the net magnitude and direction of the force using arrows |
