Dynamic brake

Okay kiddo, imagine you are running as fast as you can and you suddenly see a big wall blocking your way. What can you do to stop without crashing into it? That's when a dynamic brake comes in!

A dynamic brake is a device that helps trains, buses, and other vehicles slow down or stop by using a different source of power than what they usually use to move. Just like how you pull your legs back to stop when you're running too fast, these vehicles use this brake to slow their movement down.

When these vehicles are moving, they create a lot of energy, which is a lot of power that needs to go somewhere. A dynamic brake channels that power into something called a resistor, which is a special kind of object that allows the energy to flow through it but slows it down at the same time.

It's like pouring water into a funnel with a lot of small holes at the bottom. The water flows through, but it takes longer to come out the other side because it has to go through all those small holes first. This is how the dynamic brake slows down the train or vehicle.

In summary, a dynamic brake is a tool that helps vehicles slow or stop by redirecting the energy they create while in motion into a resistor. Think of it like putting on the brakes, but instead of using your feet, it uses science to slow down the vehicle.
