 Objects tend to continue the motion they already have unless they are acted on by forces Newton's first law  Is a push or pull, or any action that has the ability to change motion Force  Property of an object that resists change in its motion Inertia  Metric unit of force Newton  Is used to describe the total of all forces acting on an object  Net force  The rate of change in velocity; at which your speed increases Acceleration  Describe the motion that is slowing down  Deceleration  Relates the net force on an object, the mass of the object, and the acceleration  Newton's second law  It is accelerating due to the force of gravity and no other forces are acting on it  Free fall  Objects in free fall on Earth accelerate downward at 9.8 m/sec2  Acceleration due to gravity  Is speed with direction; rate of motion and the direction  Velocity  Force of gravity on an object (mass* acc of gravity) Weight  Acts against the direction of the object's motion/ fluid friction opposing the motion of an object moving through it Air resistance The maximum speed reached by an object in free fall; the speed at which the forces of gravity and air resistance are equal  Terminal speed  A line is the ration of the rise over run Slope AuthorSypes ID169643 Card SetPhysics- 2 vocab DescriptionPhysics Chapter 2 vocab Updated2012-09-08T20:51:01Z Show Answers
