A stressed out mom just purchased a cup of Starbucks coffee the bus she is riding on to work goes around the sharp curve even though she holds the cup still the coffee still splashes out which word explains this phenomenon friction gravity interior or density
The word that explains this phenomenon is "friction."
The word that explains this phenomenon is "friction." Friction is the force that opposes the motion of two surfaces in contact with each other. In this case, when the bus goes around the sharp curve, there is a sudden change in direction, causing the cup of coffee to shift its position. Due to the inertia of the liquid inside the cup, it tends to continue its motion in a straight line while the cup moves in a different direction. This difference in motion creates a force of friction between the cup and the coffee, causing the coffee to spill out of the cup.
The word that could explain this phenomenon is "friction." Friction is the force that opposes the relative motion between two surfaces in contact. In the case of the mom holding the cup of coffee, as the bus goes around a sharp curve, it experiences a change in direction. This change in direction causes the mom's hand to move sideways, while the coffee inside the cup tends to maintain its original position due to inertia. As a result, there is a relative motion between the cup and the coffee. This relative motion creates friction between the coffee and the inside of the cup, leading to the coffee splashing out.
In order to prevent this from happening, the mom could increase the friction between the coffee and the cup by using a lid or a heat-resistant grip on the cup, ensuring a tighter grip and reducing the relative motion between the coffee and the container.
