newtons second law

• Describes what an acceleration is


  rate at which velocity changes with time, in terms of both speed and direction
• list the factors that affect the acceleration of an object


  the size of the force, the direction in which the force acts, and the mass of the object
• recall the equation that relates the factors affecting acceleration

  a = f (net) / m, where a = acceleration, f (net) = the net force acting on the object, m = the mass of the object.
• use the equation relating force mass and acceleration

  F=ma

  F= force

  m= mass

  a= acceleration
• change the subject of the equation relating force mass and acceleration

  force equals mass times acceleration (F=ma). To calculate mass, rearrange the formula as mass equals force divided by acceleration (m=F/a). To calculate acceleration, rearrange the formula as acceleration equals force divided by mass (a=F/m).
• Explain what inertial mass is


  the ratio of force over acceleration.. Inertial mass is a measure of how difficult it is to change the velocity of an object
