According to Newton's second law of motion, if we have a rigid, unchanging mass and we observe it accelerating, what must be happening? Question 15 options: A force is being applied to the mass No force was or is being applied to the mass The mass MUST be changing A force was not applied.

Respuesta :

Newton's second law defines the force of an object depending on its mass and acceleration.

The rigid of constant mass is accelerating, so the force is being applied to the mass. Statement A is the correct representation.

Newton's Second Law of Motion

Newton's second law of motion states that the force applied to an object is equivalent to the product of the mass and acceleration of the object.

[tex]F = ma[/tex]

Here, F is the force applied, m is the mass and a is the acceleration of the object.

Given that a rigid has constant mass and is accelerating.

According to Newton's second law of motion, the force is given as,

F = ma

It means that the force is applied to the mass of the rigid. Statement A is the correct representation.
