According to Newton's First Law of Motion, which property of an object describes its resistance to changes in its state of motion (i.e., its velocity)?

A Momentum

B Inertia

C Velocity

D Acceleration

✓ Correct Answer: Option B

Newton's First Law, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Inertia is the property that quantifies this resistance to change in motion.

💡 Why is B) the correct answer?

The correct answer to the question "According to Newton's First Law of Motion, which property of an object describes its resistance to changes in its state of motion (i.e., its velocity)?" is Option B: Inertia.

The other options — A) Momentum, C) Velocity, D) Acceleration — are incorrect for this IB Exam Prep question. As explained above: Newton's First Law, also known as the Law of Inertia, states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted up…
