A Matter of Real Gravity Version 2

Forces in Motion SECTION 1 Vocab Match Match the following terms with their definitions. When GRAVITY is the ONLY force acting on an object Free Fall When the Upward Force of Air Resistance EQUALS the Downward force of Gravity Terminal Velocity The CURVED PATH traveled by a thrown baseball is an example of: Projectile Motion Fluid Friction that opposes motion Air Resistance The Acceleration of a FALLING object is caused by the force of: Gravity Forces in Motion SECTION 2 Vocab Match Match the following terms with their definitions. The tendency of an object to RESIST a CHANGE in Motion Inertia Property of a MOVING object that depends on it's MASS and VELOCITY Momentum LAW that states that an object at REST stays at REST and an object in MOTION stays in MOTION, UNLESS an UNBALANCED FORCE acts on it. First Law of Motion LAW that states that an object's ACCELERATION depends on its MASS and the amount of FORCE put on it. Second Law of Motion LAW that states that for every ACTION there is an OPPOSITE and EQUAL REACTION Third Law of Motion LAW that says when 2 or more objects INTERACT, they may EXCHANGE MOMENTUM, but the total momentum stays the SAME. Law of Conservation of Momentum LAW SORTING (There are TWO facts for EACH LAW!) Sort the facts into the Laws they describe. 1st Law of Motion An Unbalanced Force is required to Change an object's motion. Objects in motion want to stay in motion, and objects at rest want to stay at rest. 2nd Law of Motion An object's Acceleration depends on its Mass and the Force exerted on it. Force = Mass x Acceleration 3rd Law of Motion Forces occur in PAIRS. For every action, there is an OPPOSITE and EQUAL Reaction. Law of Conservation of Momentum When 2 or more objects Interact, they may Exchange Momentum The Total amount of Momentum stays the SAME when objects interact.
