Which Direction Do Raindrops Move When Using Wipers?
2 Answers
When raindrops fall on the windshield, the car wiper moves upward towards the passenger side, and downward towards the edge and lower part of the driver's side windshield. Using wipers on rainy days ensures clear visibility for the driver and enhances driving safety. Precautions for using car wipers include: 1. Avoid dry friction of the wiper as much as possible. 2. Clean dust before using the wiper. 3. Try to avoid prolonged exposure to high temperatures. The wiper is made of rubber, and prolonged exposure to high temperatures can cause deformation and loss of elasticity, leading to ineffective cleaning. 4. Maintain a reasonable speed. Use the wiper at a steady speed to prevent damage.
Where raindrops go in the rain depends on the wind direction! When there's no wind, raindrops fall straight down, but it's different when the wind blows. When cycling against the wind, raindrops hit your face directly, making it hard to hold an umbrella; walking with the wind makes the rain feel lighter. When standing near buildings, those tall structures alter the wind's path, causing raindrops to drift chaotically with the wind, often hitting windows at an angle. Sometimes, strong winds blow raindrops sideways, moving faster than windshield wipers can keep up. Especially during summer thunderstorms, raindrops may fall vertically one moment, then suddenly shift direction with a gust of wind, changing the entire rain curtain's trajectory.
