What is the term used to describe the resistance of any physical object to any change in its velocity, including changes to its speed or direction of motion?

A. Momentum
B. Inertia✓ Correct Answer
C. Torque
D. Impulse

💡 Solution & Explanation

Inertia is the fundamental property of matter defined as the resistance of any physical object to any change in its state of motion or rest, as formulated by Newton in his first law. Options like momentum refer to the product of mass and velocity, while torque and impulse represent rotational turning force and force applied over time respectively.
