Answer:
11. A
Explanation:
Inertia is the tendency of an object to resist changes in its state of motion.
12. B
Explanation:
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.
13. B
Explanation:
Putting Acceleration in Conceptual terms: Acceleration is a quantity in physics that is defined to be the rate of change in the velocity of an object over time. Since velocity is a vector, acceleration describes the rate of change in the magnitude and direction of the velocity of an object.
