Question

write out newton’s three laws of motion in terms of what happens with the momentum of objects.
newton’s first law
○ momentum is conserved when two or more objects interact.
○ the momentum of an object remains constant unless acted upon by a force.
○ momentum is equal to mass times velocity.
○ momentum is equal to mass time acceleration.
○ the rate of change of the momentum of an object is equal to the force producing the change.
newton’s second law
○ momentum is conserved when two or more objects interact.
○ the momentum of an object remains constant unless acted upon by a force.
○ momentum is equal to mass times velocity.
○ momentum is equal to mass time acceleration.
○ the rate of change of the momentum of an object is equal to the force producing the change.
newton’s third law
○ momentum is conserved when two or more objects interact.
○ the momentum of an object remains constant unless acted upon by a force.
○ momentum is equal to mass times velocity.
○ momentum is equal to mass time acceleration.
○ the rate of change of the momentum of an object is equal to the force producing the change.

Explanation:

• Newton's First Law (Law of Inertia): An object's momentum (or velocity, since \( p = mv \)) remains constant unless a net force acts on it. So the correct option is "The momentum of an object remains constant unless acted upon by a force."
• Newton's Second Law: The rate of change of momentum (\( \frac{dp}{dt} \)) equals the net force. So the correct option is "The rate of change of the momentum of an object is equal to the force producing the change."
• Newton's Third Law (Law of Action - Reaction): When objects interact, momentum is conserved (total momentum before = total momentum after). So the correct option is "Momentum is conserved when two or more objects interact."

Answer:

Newton's first law: The momentum of an object remains constant unless acted upon by a force.
Newton's second law: The rate of change of the momentum of an object is equal to the force producing the change.
Newton's third law: Momentum is conserved when two or more objects interact.
