 The amount of matter an object has; a measure of an object's inertia; measured in g or kg  Mass  Is the distance it travels divided by time it takes  Speed  Is speed with direction over rate of motion and the direction  Velocity  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  The rate of change in velocity; rate at which your speed increases Acceleration  It is accelerating due to the force of gravity and no other forces are acting on it  Free fall  The speed at a pacific time  Instantaneous speed  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  Whenever one object exerts a force on another, the second object exerts an equal and opposite force on the first  Newton's third law  A speed that does not change  Constant speed  The action of moving or of changing place or position  Motion  The force of attraction on an object on another Gravity The total distance traveled divided by the total time elapsed  Average speed  Two equal forces are applied on an object pushing both ways  Balanced force  Forces that produce a non zero net force, which changes an object's motion Unbalanced force AuthorSypes ID169645 Card SetPhysics- Study guide 2 vocab DescriptionPhysics- Study Guide 2 vocab Updated2012-09-08T21:20:47Z Show Answers
