Which of the following statements correctly describes Newton's first law of
motion?
A.The forces acting on an object are paired with equal and opposite forces.
B. An object in motion will stay in motion, and an object at rest will stay at rest
unless an external force is applied to it.
C.There is a relationship between an object's mass, its acceleration, and the
applied force.

Respuesta :

The correct answer is B. An object in motion will stay in motion, and an object at rest will stay at rest unless an external force is applied to it.

Explanation: This statement accurately describes Newton's first law of motion, which is also known as the law of inertia. It asserts that an object will maintain its state of motion (either at rest or in uniform motion) unless an external force acts upon it.
