newton's second law

• What is acceleration directly proportional to?


  Resultant force
• What is acceleration inversely proportional to?

  the mass of the object
• What is Newton's second law?

  Force = mass x acceleration

  
  

  F = MA
• What is inertia?


  The tendency of an object to resist a change in motion
• What does inertia measure?

  How difficult it is for the object to change its velocity
• How do you calculate inertial mass?

  inertial mass = force/acceleration

  
  

  F / A
