Question

when brakes are applied suddenly, the coffee in a cup resists the change in motion and spills forward. what property of matter is responsible for this behavior? magnetism friction inertia gravity

Explanation:

Inertia is the property of matter that resists changes in its state of motion. When the brakes are applied suddenly, the cup (attached to the vehicle) stops, but the coffee (due to inertia) continues moving forward, causing it to spill. Magnetism involves magnetic forces, friction is a force opposing motion between surfaces, and gravity is the force attracting objects. None of these directly explain the coffee's forward - spilling motion like inertia does.

Answer:

Inertia
