 States that every action force creates a reaction force that is equal in strength and opposite in direction Newton's third law  The mass of an object multiplied by its speed or velocity  Momentum  A change in momentum created by a force exerted over time  Impulse  Total momentum in a system of interacting objects cannot change as long all forces act only between the objects in the system  Law of conservation of momentum  Is a quantity that measures the ability to cause change  Energy  Unit of measurement for energy kgm2/s2 Joule  The transfer of energy that results from applying a force over a distance  Work  Energy due to position (something is capable of becoming active) Potential energy  Energy of motion (objects that are moving also have the ability to cause change) Kinetic energy  Idea that energy converts from one form into another without a change in the total amount  Law of conservation of energy  Occurs when two or more objects hot each other Collision  Object bounce off each other with no loss in the total kinetic energy of the system Elastic collision  Objects change shape or stick together, and the total kinetic energy of the system decreases Inelastic collision A line is the ratio of the rise (vertical change) to the run (horizontal change) Slope AuthorSypes ID171225 Card SetPhysic- 3 vocab DescriptionPhysics- 3 vocab Updated2012-09-16T19:00:28Z Show Answers
