  ### Newton's First Law
  
  Objects remain at rest and objects in motion remain in motion unless acted upon by an unbalanced force
  
  ### Newton's Second Law
  
  The acceleration of an object increases with increased force and decreases with mass
  
  ### Newton's Third Law
  
  When an object exerts force on an another object, the second object exerts an equal opposite force onto the first object
  
  A push or pull
  
  ### Centripetal force
  
  A force that keeps an object moving in a circle
  
  ### Net Force
  
  The overall forces combined
  
  ### Two ways to increase the acceleration of an object
  
  Reduce mass and increase force
  
  MA x 100
  
  ### How does a machine make work easier
  
  Changes the direction
  Changes the size of the force
  
  ### When is power increased
  
  More work is done in a given amount of time
  The time it takes to do work is decreased
  
  ### Examples of a lever
  
  Wheelbarrow and scissors.
  
  Ramp
  
  Knife
  
  Wagon
  
  Jar Lid
  
  Clothes Line
  
  ### Why are simple machines so useful?
  
  The decrease the amount of work needed and have a mechanical advantage
  
  ### First Class Lever
  
  A lever where the fulcrum is in the middle, the input force is on the left, and the resistance force (output force) is on the right
  
  ### Second Class Lever
  
  A lever where the fulcrum is on the far left, the resistance force is on the right, and the input force is on the far right
  
  ### Third class lever
  
  A lever where the fulcrum is on the far left, the input force is on the right, and the resistance force is on the far right.
  
  ### Input force
  
  The force put on by the human
  
  ### Output force
  
  the force done by the machine
  
  ### Examples of First Class Lever
  
  See Saw, Scissors
  
  Wheelbarrow
  
  ### Examples of Third Class lever
  
  Fishing Rod, Catapult
  
  Wheel and Axle
  
  ### Examples of Compound Machines
  
  Can Opener, Scissors
  
  ### Compound Machines
  
  A Machine that had two or more simple machines
  
  ### Lever
  
  A Machine that has a fulcrum, or a bar that pivots at a fixed point
  
  ### Inclined Plane
  
  A simple machine that is a straight, slanted surface
  
  ### Wedge
  
  A double inclines plane that moves
  
  ### Screw
  
  An inclines plane that is wrapped in a spiral
  
  ### Wheel and Axle
  
  A simple machine consisting of two circular objects of different sizes
  
  ### Pulley
  
  A simple machine consisting of a grooved wheel that holds a rope or cable
