What is inertia?
Show answer & explanation
Correct answer: B
Explanation
Inertia is the natural property or tendency of an object that causes it to resist any change in its state of rest or uniform motion.
It is the basis of Newton's first law, which states that an object's state does not change unless an external force is applied.
Key details:
Mass relation: The inertia of an object depends on its mass; greater mass means greater inertia.
Example: Passengers in a moving bus lean forward when the brakes are suddenly applied because the body wants to maintain its state of motion.
Types: It can be inertia of rest, inertia of motion, and inertia of direction.
