Newton's Second Law

    Cards (9)

    • What is Newton's second law?
      The acceleration of an object is proportional to the resultant force acting on the object and inversely proportional to the mass of the object
    • What happens to an object if its resultant force is doubled?
      Its acceleration will be doubled
    • What happens to an object if its mass is doubled?
      Its acceleration will be halved
    • What the equation for Newton's second Law?
      Force = mass x acceleration
    • Mass is a measure of what?
      Inertia
    • To accelerate from a main road to a motorway, what is the typical acceleration involved?
      2 m/s ² (For a typical family car, that would require a force of 2000 N)
    • What is the inertial mass of an object?
      A measure of how hard it is to change the velocity of an object
    • An object with a larger inertial mass will require a larger force to change the velocity
    • What is the ration that inertial mass is given by?
      Force over acceleration
