Newton’s 1st & 2nd Law + 3rd.

• Newton's first law


  A resultant force is required to change the motion of an object
• If there isn't a resultant force, the object's motion won't change
• Newton's second law


  If a non-zero resultant force acts on an object, it will cause the object to accelerate
• Newton's second law equation

  Force = Mass x Acceleration
• Inertia is the tendency for the motion of an object to remain unchanged
• Inertial mass measures how difficult it is to change an object's velocity
• Any Change In The Direction Of The Object, Will Change The Velocity
• The size of the resultant force is directly proportional to the acceleration of the object.
