Why Does Rain Hit the Windshield More When the Car is in Motion?

Have you ever wondered why rain seems to hit your car's windshield more aggressively when it's moving compared to when it's stationary?

Let's delve into the fascinating world of aerodynamics, physics, and engineering to unravel this captivating phenomenon.

Vertical and Horizontal Components

When standing still in the rain, only the vertical raindrops will land on you.

However, when your car is in motion, the combination of vertical and horizontal raindrops creates a more significant impact on the windshield.

The Rain Principle

The science behind it is simple yet intriguing.

As the car moves forward, the rain hits the windshield both from above and from the front, contributing to a greater impact of rain on the windshield when the car is in motion.

The Engineering Factor

The aerodynamics of the vehicle is a crucial aspect to understand why rain hits the windshield more when the car is in motion.

At higher speeds, the slanted angle of the windshield and the force of the moving car cause rain to be more effectively intercepted and distributed over the surface, leading to increased rain accumulation.

The Wiper Solution

To address the issue of rain accumulation on the windshield while driving, automotive engineers have developed windshield wipers.

These devices efficiently remove the excess rain, ensuring clear visibility for the driver.
