You are driving to a birthday party with the cake sitting in the passenger's seat. You slam on your brakes to avoid hitting a deer. This causes the cake to splatter all over your dashboard and the floor of the passenger's side. Which of Newton's Laws best explains why this happens?

• Newton's First Law (Inertia)

• Newton's Second Law (Net force = mass x acceleration)

• Newton's Third Law (Action/Reaction)

• Law of Universal Gravitation

A car with a velocity North encounters a force pushing it South. Ignoring all other factors, what will the motion of the car do?
