Inertia
The word that explains this phenomenon is inertia.
The phenomenon described in this situation can be explained by the concept of inertia.
Inertia is the property of matter that causes an object to resist changes in its motion. It is related to Newton's first law of motion, which states that an object at rest tends to stay at rest, while an object in motion tends to stay in motion with the same speed and in the same direction, unless acted upon by an external force.
In the case of the Mom holding the cup of Starbucks coffee, when the bus goes around a sharp curve, the bus and everything inside it experience a change in direction. However, the coffee inside the cup wants to keep moving in a straight line due to its inertia. As a result, the coffee splashes out of the cup because it has not adjusted to the change in direction of the bus.
Therefore, the word that explains this phenomenon is "inertia."
