Science Topic 2 Newton's Laws of Motion 2011

Newton's First Law (definition) Law of inertia: An object will remain at rest or will not change its speed unless it is acted upon by an outside, unbalanced force
Newton's Second Law (definition) F=ma: Describes how the mass of an object affects the way that it moves when acted upon by one or more forces
Newton's Third Law (definition) Action/reaction: For every action there is an equal and opposite force
Law of inertia (example) Seatbelts keep passengers moving with the vehicle to prevent the law of inertia
F=ma (example) As a rocket accellorates, it loses mass but retains the same force thus increasing its accelleration
Action/reaction (example) Our weight on the floor (downwards) is countered by the upward force of the floor, otherwise we would fall through
