Question

which law of physics explains why coffee spills forward when a car suddenly stops? newtons third law of motion (action and reaction). newtons first law of motion (the law of inertia). newtons second law of motion (the law of acceleration). law of conservation of energy

Explanation:

Newton's first law of motion (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. When the car suddenly stops, the coffee (which was in motion along with the car) continues to move forward due to its inertia.

Answer:

Newton's first law of motion (the law of inertia).
