Question

Which of the following situations describes inertia?

1) I. A moving object tends to resist a change in direction.
2) II. A moving object tends to resist a change in speed.
3) III. A stationary object tends to resist being moved.
4) IIII. All the Above

Answer 1

Inertia is the tendency of an object to resist changes in its state of motion, which is reflected in situations where moving objects resist changes in speed or direction, and stationary objects tend to remain at rest. The correct answer to the question is 'All the Above', as all options describe inertia.

Step-by-step explanation:

The concept of inertia is fundamental in physics, particularly when discussing Newton's First Law of Motion. The law states that a body at rest will remain at rest, and a body in motion will continue to move at a constant velocity unless acted upon by a net external force. This tendency of an object to resist changes in its state of motion is known as inertia.

Thus, all the following situations describe inertia:

1. A moving object tends to resist a change in direction.
2. A moving object tends to resist a change in speed.
3. A stationary object tends to resist being moved.

Therefore, the correct answer is 'All the Above,' as they all are manifestations of the same principle of inertia, which is inherently related to an object’s mass—the quantity of matter in a substance.
