Rolling objects are accelerated by a force, which is a push or a pull. Out of the given choices, only Option B - Inertia correctly describes a property that is related to acceleration. Inertia is the tendency of an object to maintain its current state of motion. When a rolling object is pushed or pulled, it will resist the change in motion, causing it to accelerate. Friction (Option A) is a force that resists motion, and although it can affect the acceleration of rolling objects, it is not the main cause of the acceleration. Momentum (Option C) is the product of an object's mass and velocity, which can affect its acceleration, but it is not the action causing the acceleration. Gravity (Option D) is a force that attracts objects towards each other, but it does not directly cause the acceleration of rolling objects. Therefore, Inertia (Option B)
