15.- Si sobre un objeto se aplican tres fuerzas de diferentes magnitudes, ¿cuál es la fuerza resultante sobre el objeto?
El resultado de la fuerza mayor menos la fuerza menor.
C) La suma aritmética de las tres fuerzas.
B) El promedio matemático de las tres fuerzas.
D) La suma vectorial de las fuerzas.



Answer :

Final answer:

In physics, the net force on an object from multiple forces is the vector sum of the individual forces. Vector addition is essential to determine resultant forces accurately.


Explanation:

When multiple forces act on an object, the net force is the vector sum of the individual forces. The resultant force is determined by adding the vectors together, considering both magnitude and direction.

For example, if a 5N force acts eastward and a 3N force acts northward on an object, the resultant force will be a 2N force at a specific angle based on vector addition.

Vector addition in physics is crucial to accurately determine the net effect of multiple forces on an object's motion.
