4.- "Todo cuerpo mantiene su velocidad contante hasta que una
fuerza exterior no equilibrada actúe sobre él" es el enunciado
de
A) primera ley de Newton.
B) principio de acción y reacción.
C) principio de conservación de la cantidad de movimiento.
D) tercera ley de Newton.



Answer :

Final answer:

Newton's first law of motion states that objects maintain their states of rest or motion unless acted upon by an external force.


Explanation:

Newton's first law of motion, also known as the law of inertia, states that a body at rest will stay at rest, and a body in motion will stay in motion at a constant velocity unless acted upon by an external force. This law highlights the concept of inertia, which is the tendency of an object to resist changes in its state of motion. For example, a moving car will continue moving forward unless a force (like friction or braking) acts on it to stop it.
