newtons laws

• describe newtons first law

  zero resultant force on stationary object remains stationary and on moving object remains moving at same velocity
• describe affect of non zero force

  cause object to accelerate or deaccelerate
• describe inertia 


  tendency of object to remain in state of rest or uniform motion
• describe newtons second law

  acceleration of object directly proportional to force applied and inversely proportional to mass
• describe inertial mass 


  measure of how difficult it is to change velocity of object
• describe newtons third law

  forces exerted between objects are equal in magnitude and opposite in direction
