Bernoulli’s principle refers to a law in physics that once the speed of a liquid or gas increases, the corresponding pressure also decreases. With this principle, fluids or gas particles for example are said to have a faster pace as long as the pressure within is also lowered. This particular law or principle was discovered by Daniel Bernoulli back in 1738 and used in various fields like aerodynamics and hydrodynamics.

To simply Bernoulli’s principle, many would give the water pipe as a classic example. If the water pipes for example has the same size and diameter all throughout their length, water or some other fluid will simply flow evenly at a regular pace. If the pipe becomes smaller, the flow of water will then have to increase in terms of speed in order to get to the other end. The increase in speed will then require pressure to be decreased in order for the water to flow through the smaller pipe. If pressure is higher, the flow of water will then be impeded with the speed going down. This basic example of the Bernoulli principle is often used in the study of water or air in terms of dynamics.

The field of car racing is one area wherein the Bernoulli principle is often used in the car’s design and so-called aerodynamics. For race cars to go faster, their external design is often conceptualized and finalized with Bernoulli’s principle being considered thoroughly. As the principle suggests decreasing pressure to increase speed, certain elements of the car’s design are also configured for this specific effect. The rear spoilers and tail fins of a car are examples of external design concepts that help reduce pressure or drag from the air and therefore helping the car increase its speed. The same principle is also being used in the design of sailboats that aim to go faster as it travels through the water. The less pressure is generated on the actual machine or the sailboat, the higher the chances of increasing speed as it travels through the water.
