Cards Term Newton's 2nd Law Definition says a net force acting on an object causes the object to accelerate in the direction of the net force. Depends on: Mass of the object and the size of the force Term Air Resistance Definition a force air exerts on a moving object. Depends on speed, shape, size and denisty of an object. Term Terminal Velocity Definition the highest velocity reached by a falling object. Term Projectile Definition anything that is shot or thrown through the air ex. spit wad Term Centripetal Acceleration Definition Acceleration toward the center of a curved or circular path Term Centripetal Force Definition is a force acting toward the center of a curved or circular path Term Artificial Satellite Definition are human-made devices that orbit the Earth for specific purpose Term Newton's Third Law of Motion Definition describes action-reaction pairs this way: When one object exerts a force on a second object, the seconds one exerts a force object on the fist one that is equal in size and opposite in direction. Term Momentum Definition is a property a moving object has because of its mass and velocity. Term Law of Conservation of Momentum Definition states that the total amount of momentum of a group of objects does not change unless outside forces act on the objects.
