    • Newton’s first law questions will usually be discussion questions.
    • Newton’s second law can be asked on its own or it, often, will be asked in conjunction with Newton’s third law. 
      • When setting up equations for a 2-body or 3-body system, an equation for each object is set up separately. 
      • YOU ARE NOT ALLOWED TO TREAT THE TWO OBJECTS AS ONE IN THE SYSTEM. 
      • Solve the equations simultaneously to calculate the unknown quantities. 
      • Remember that tension in a string, cable or even stick (wooden, metal etc.) is constant throughout. It is also noteworthy that the acceleration of all the objects are the same while connected to one another.

  • Friction = the force that opposes motion
  • Friction coefficient = a measure of the "stickiness" of two types of surfaces in contact
  • The larger the coefficient of friction, the more they will "stick" to each other and therefor will move more difficultly across each other.
  • If an object is at rest on an inclined plane without slipping, then friction must equal the component of the weight of the object parallel to the incline. This requires greater and greater friction for steeper slopes.
