WS1.1. Newton's law of motion - Intro

Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. More precisely, the first law defines the force qualitatively, the second law offers a quantitative measure of the force, and the third asserts that a single isolated force doesn't exist.

Select the correct statements regarding the Newton's law:

(a)

In an inertial frame of reference, the vector sum of the forces $F$ on an object is equal to the mass $m$ of that object multiplied by the acceleration $a$ of the object (assuming a constant mass).

(b)

In an inertial frame of reference, an object remains at rest unless acted upon by a force.

(c)

In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force.

Select all possible options that apply.
