What causes a coasting vehicle in motion to eventually stop?

• A. Gravity
• B. Air resistance
• C. Pavement type
• D. Friction

Answer: (D)

A coasting vehicle eventually stops due to the effects of friction acting on it. When a vehicle is in motion and coasts, it encounters various forms of friction that oppose its motion. This can include friction between the tires and the road surface, as well as internal friction within the vehicle's components. Friction is a force that resists the sliding motion of surfaces relative to one another. In the case of a vehicle, as it moves, the friction between the tires and pavement slows it down, causing it to come to a stop over time. This principle is fundamental in physics and applies universally to all moving objects, explaining how they lose kinetic energy and eventually halt. Although gravity may influence this process, especially on inclines, and air resistance also plays a role in slowing down vehicles, the primary factor in bringing a coasting vehicle to a stop is friction. The type of pavement may affect the coefficient of friction, but it does not fundamentally change the fact that friction is what ultimately causes the vehicle to stop. Therefore, understanding the role of friction is essential in comprehending the dynamics of motion for vehicles and other objects.
