Force : Push or pull Newton: unit to measure force Net force: combination of force Unbalance force: object start moving Balance force: object doesn`t move

Friction : They rub against each other Gravity: force that pulls objects down Mass: amount of matter in an object Weight: force according to gravity Air resistance: opposite force against gravity

First Newton`s law: Any object at rest remain at rest and any object that moves will keep moving until a force act over it Second Newton`s law: acceleration depends on the mass and the applied force Inertia : resist to a motion`s change Third Newton`s law: If one force exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object.

Pressure: relationship between force over an specific area. Pascal: unit to measure pressure

Bernoulli`s: states that the faster a fluid moves, the less pressure the fluid exerts.
