It 8 of 15 Ineastic collinson A collinson in which kinetic energy is not conserved 9 of 15 Inertia The measure of how difficult it is to change an object's velocity 10 of 15 Momentum Mass x velocity 11 of 15 Net force The force when tow or more forces are added together as vectors 12 of 15 Newton's First Law The motion (speed an direction) of an object does not change when the resultant force is zero 13 of 15 Newton's Second Law If the resultant force is not zero the motion of an object (speed or direction) changes 14 of 15 Newton's Third Law Forces come in pairs: the force of Y on Y and the force of Y on X 15 of 15
