I hope you enjoy this Gallerie!!!!!!!!!!!!!!!!
Announce!
I dicovered that if we improve in the future the Science ,We can make the difference.Come on We can make the change and change the world with our knowledge.
We can make the DIFFERENCE!!!!!!!!!!!!
Senteces of vocabulary # 1,2,3.
- Force:They are applying all their force in that box.
- Friction:When a wheel touch the ground it create friction.
- Drag force: When a skydriver is falling down ther is apply the drag force.
- Gravity:something fall down why? because the gravity.
- Net Force:We are trying to put all our net force in this game.
- Balanced Force: I apply the balanced force when there is the same mass and distance so the force is cancel.
- Unbalanced Force:When there is the same mass but different distance so the force is not cancel.
- Inertia:The Inertia makes something continues moving.

Autors`s information
Hello, my name is Rosa María Bernal and I am the author of this blog. Ihope you enjoy my blog and learn Science words.
How levers work (Vocabulary#3)

- Effort force: The force applied to a machine.
- Resistance Force:The force that a machine acts against.
- Lever: A simple machine made of a rigid bar on a pivot point.
- Fulcrum: The pivot point of a lever.
- Mechanical advantage:The number of times a machine multiplies the force applied.
- Pulley:A grooved wheel that turns by the action of a rope in the groove.
- Wheel and axle:A simple machine made of a handler or axis attached to the canter of a wheel.

Energy and Work (Vocabulary#2)
- Potential energy:The energy stored in an object or material.
- Gravitational potential energy:The potential energy of an object located above the ground.
- Kinetic energy: the energy of a moving object.
- Work:Force applied to an object times the distance the object moves.
Forces and Newton`s First Law
Force: a push or pull exerted by one object on another.Friction: A force that opposes the motion in contact
with a surface.
Drag force: A force that opposes the motionof an object through a liquid or gas.
Gravity: a force of attraction that exist between all 
objects with mass.
objects with mass.Net Force:The combined effect of all the forces acting on an object.
Balanced forces:Forces that cancel each other out when
acting together on a single object.
Unbalanced forces:Forces that do not cancel each other out when acting together on a single object.
Inertia:The tendency of an object to oppose a change in motion.
Momentum:The mass of an object multiplied by its velocity.
