Question

question 2 of 25 which of the following statements describes the law of inertia? a. the force of friction on an object is proportional to the normal force. b. objects remain in the same state of motion unless a force acts on them. c. for every action force there is an equal and opposite reaction force. d. net force is equal to mass times acceleration.

Explanation:

The law of inertia, also known as Newton's first - law of motion, states that an object will remain at rest or in uniform motion in a straight line unless acted upon by an external force. Option A describes the relationship between friction and normal force. Option C is Newton's third - law. Option D is Newton's second - law.

Answer:

B. Objects remain in the same state of motion unless a force acts on them.
