Question

which of newtons laws of motion is a statement of the conservation of momentum?
a the first law
b the second law
c the third law
d the seventh law

Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. When considering a system of two interacting objects, the forces they exert on each other are equal and opposite. By integrating these forces over time (using the impulse - momentum theorem \(J = F\Delta t=\Delta p\)), we can show that the total momentum of an isolated system (where the only forces are internal forces between the objects in the system) is conserved.

Newton's First Law is about an object's state of motion (remaining at rest or in uniform motion unless acted on by a net external force). Newton's Second Law is \(F = ma\) (relating force, mass, and acceleration). There is no "Seventh Law" in Newton's Laws of Motion.

Answer:

C. The Third Law
