... because of your inertia. II. When a bus suddenly stops, the coffee in a person's cup appears to be forced forward. The coffee in the cup continues to move forward at the speed the bus was travelling at, but the bus is slowing down, so the coffee moves forward relative to the bus. III. When traveling ...
