Question

When any vehicle moves very fast, low pressure is created along its top.

• A. low pressure
• B. high pressure

Answer 1

The correct option is A

low pressure

According to the Bernoulli's principle, air pressure decreases when the velocity of air increases and air pressure increases when the velocity of air decreases.
This fact has been applied in an aeroplane flying, the wings generate most of the lift to hold the plane in the air. The pressure above the wing is lower than the pressure below, and this creates the upward thrust that powers the plane upward. Similarly, when any vehicle moves with a high velocity, a region of low pressure is created along its tops.
