Final answer:
Blasts of wind from larger vehicles fall under the topic of Fluid Mechanics and specifically the study of Aerodynamics in Physics.
Step-by-step explanation:
The subject related to the question is Physics. Blasts of wind from larger vehicles fall under the topic of Fluid Mechanics and specifically the study of Aerodynamics.
When a larger vehicle passes by, it creates a disturbance in the surrounding air, resulting in a blast of wind. This blast of wind can affect nearby objects and people. The characteristics of the wind blast, such as its speed and direction, can be analyzed using the principles of fluid dynamics and aerodynamics.
