Answer:
Question:
3. Newton's First Law - The Law of Inertia: In the absence of a new external force, an object's state of
motion will remain constant
Answer:
Question:
4. Newton's Second Law - The Law of Force and Acceleration: 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.
Answer:
Question:
5. Newton's Third Law - The Law of Universal Gravitation: To every action there corresponds an equal and
oppositely directed reaction.
Answer:
Question:
6. Laws of Inertia (Newton's First Law): Objects that are at rest tend to stay at rest, and objects that are
moving tend to keep moving unless something changes the state of motion
Answer:
Question:
