If the air moves faster above an object, it creates a lower pressure area. In response, the higher pressure beneath the object will push it upward. This mechanism is known as lift and is how airplanes generate the force needed to fly.
Downward.
If the air moves faster below an object, the pressure is lower compared to the pressure above the object. This pressure difference creates lift, causing the object to be pushed upwards.
Lightning strikes downward from the clouds to the ground.
