Definition Distance Term what is the distance an object has moved and the direction an object has moved in position from the starting point? Definition Displacement Term This must be specified in order to determine if an object has changed position. Definition A Referance Point Term The Equation for Speed is Definition Speed equals Distance/Time Term The speed and direction of a moving object shows it's Definition Velocity Term What occurs when an object changes speed or changes it's direction? Definition Acceleration occurs Term An object speeds up if it's acceleration is Definition in the same direction of it's motion Term An object slows down if its acceleration is Definition in the opposite direction of its motion Term The Equation for Acceleration is Definition Final Velocity - First Velocity / The amount of Time taken Term What is Force Definition Force is a push or a pull Term What is the combination of all the forces action on an object? Definition The object's Net Force Term When is the force on an object blanced Definition when the net force is zero. Term What is Inertia Definition the resistance of an object to a change in motion. Term What is Newton's First Law of Motion Definition The motion of an object won't change unless an unbalanced net force acts on it. Term What is Acceleration Definition The rate at which the Veolocity (Speed and direction) of an object changes. Term What is Instantaneous Speed Definition The speed at a given point in time. Term What is Velocity Definition The speed of an object and the direction of its motion.
