Newton’s Laws Helpful study aid

Newton’s 1st Law The Law of Inertia “ a body at rest remains at rest and a body in motion remains in motion with a CONSTANT speed and in a straight line, UNLESS acted upon by an outside force.

Newton’s 1st Law 2 parts Objects at rest Objects in motion

Newton’s 1st Law If at rest, they will continue in this same state of rest. If in motion with an eastward velocity of 5 m/s, they will continue in this same state of motion (5 m/s, East).  If in motion with a leftward velocity of 2 m/s, they will continue in this same state of motion (2 m/s, left). The state of motion of an object is maintained as long as the object isnot acted upon by an unbalanced force. All objects resist changes in their state of motion - they tend to "keep on doing what they're doing.“ As the long as the forces are not unbalanced - that is, as long as the forces are balanced - the first law of motion applies.

Newton’s 2nd Law “The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.” Go to this site (very helpful!) http://www.physicsclassroom.com/class/newtlaws/Lesson-3/Newton-s-Second-Law

Newton’s 3rd Law “For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.”
