Question

question 4 of 24. which of the following is an expression of newtons second law? a. the acceleration of an object is determined by its mass and the net force acting on it. b. objects at rest tend to stay at rest, and objects in motion tend to stay in motion unless acted on by an unbalanced force. c. objects at rest tend to stay at rest, and objects in motion tend to slow down until they come to rest. d. every force is paired with an equal and opposite force.

Explanation:

Newton's second law states that an object's acceleration depends on its mass and the net force acting on it, expressed as \( F = ma \). Option A directly reflects this relationship. Option B is Newton's first law (inertia), C is incorrect (objects in motion maintain velocity without force), and D is Newton's third law (action-reaction).

Answer:

A. The acceleration of an object is determined by its mass and the net force acting on it.
