Law of inertia (D)
Answers
Answer:
(A) Newton’s first law states that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
(B) It states that the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it.
(C) Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction.
(D)Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon by a force.
