Hypersonic effect

Imagine riding on a really fast train that can go super, super fast. When the train goes really fast, you feel wind blowing in your face and your hair might even fly around. This happens because the train is moving so fast that it causes the air to move around it really quickly.

Now, imagine something going even faster than that! When things go faster than the speed of sound (that's how fast sound travels through the air), they create what's called a "sonic boom". This is a loud noise that happens because the object is moving so fast that it creates a big pressure wave in the air. But there's something else that happens when things go really, really fast - it's called the "hypersonic effect".

The hypersonic effect is when things go even faster than the speed of sound, like five or ten times faster! When this happens, the air around the object gets really hot because of all the friction from the air rushing past it. This makes it really hard for the object to keep going that fast, because it has to fight against the heat and the air pressure.

So, when we talk about the hypersonic effect, we're talking about something going really, really fast and causing a lot of heat and pressure. Scientists study the hypersonic effect to learn more about how things can move so fast and how they can be designed to handle all that heat and pressure.
