2nd law

• 2nd law

  acceleration of object is proportional to resultant force acting on object

  acceleration of object is inversely proportional to mass of object
• force equation

  force=mass x acceleration
• inertia

  object will remain still or keep same motion unless resultant force is applied
• inertial mass

  difficulty to change velocity of mass
• larger inertial mass

  larger force to produce given acceleration
